If something at the moment of death contains the same matter as that something when alive, what is lost?
How does physicalism (physical monism) explain what that loss is?

The state of being alive is lost (that is, it ends) when something dies. The state of being alive is mostly defined by having the ability to deliver the right chemistry to the right places in the organism (for humans, the brain) at the right time at the right temperature.
Since there are many more ways for the chemical systems in your brain matter to be incompatible with life than there are for it to be living, and since the brain's living state takes a continuous supply of chemical potential energy to maintain against equilibrium, the state change is usually irreversible unless the body's self-ordering processes can be promptly restarted or duplicated with high quality CPR. Cooling the brain to slow the rate at which brain chemistry seeks equilibria incompatible with life lengthens the window of opportunity.
Monism doesn't really come into it. I've never heard of anybody getting a Do-Not-Resuscitate order or refusing deep hypothermia during cardiac surgery because they believe their soul is the boss of their chemistry.
If I turn off the ignition, my car stops. The matter content of my car is unchanged, but various processes that took place while my car was running are no longer taking place. Death is clearly analogous. When you are alive, a large number of chemical processes take place in your body, which cause, among other things, signals in your autonomous nervous system that trigger heart beats, cause you to breathe, and so on. When you die, your body chemistry changes so that key autonomous processes stop. Your heart no longer beats. Your diaphragm no longer contracts to suck in breath. Deprived of oxygen, your mental processes stop. The difference between your living body and your dead body, in terms of matter alone, is miniscule- there is slightly less oxygen in the blood. The key difference is that certain chemical reactions that took place to keep you alive no longer take place.
Where the analogy with the car ends is that the car can usually be restarted, whereas death has a tendency to be irreversible.
It's a common misconception that death is a "moment".
There are, of course, more and less sudden ways to die. But death is generally a process. Your heart stops beating, your organs shut down, your breathing stops, your brain activity decreases until it ceases.
On a simplified level, you can think of this like turning off a computer (except that it generally can't be turned on again). The electricity stops flowing and the various components stop functioning. Life is all the processes in your body, like all the processes in a computer, and those cease when you die or when you turn off the computer.
This is also very compatible with e.g. someone's heart stopping, and restarting, and them living on, but also commonly experiencing some negative effects from this, as a result of the damage of one's body (especially one's brain) starting to fail.
Note: I am not a physicalist, so I am responding from my best understanding of their position.
From a purely physicalist perspective, what is lost at the moment of death is a particular pattern--an ordered state of matter capable of sustaining biological processes. The science-fiction concept of the "transporter beam" can be viewed as a physicalist thought experiment positing that IF you could exactly reconstruct that particular pattern of matter, nothing would be lost.
It's a challenge, within physicalism, to explain the importance of the distinction between the pattern that represents a living creature and the pattern that represents a corpse. One prominent attempt to reconcile (things like) the significance of the pattern of "life" with a strict belief in physical monism is the philosophical stance called "Emergentism." This states that the patterns that emerge at higher levels of organization can have a significance that goes beyond a strictly reductive analysis of the lower-level components that compose them. (Emergence is a recognized scientific phenomenon, but what it implies is still controversial.)
Life is lost, or ends, when we die. That's just what the words factually mean
the end of the life of a person or organism.
You seem to be asking whether it can be the end of consciousness.
I personally think it cannot, but there's so much analysis necessary to show anything of the sort, about the nature of consciousness at a minimum, that it's a somewhat absurd and confusing thing to assert. I probably think that the reason I believe this has something to do with ontic vagueness, because non existence itself is not slippery enough and our consciousness is perhaps notoriously difficult to reach a clear description, let alone metaphysics, of.
Order.
On death, entropy grows quickly (entropy is not necessarily order loss, but in this case, it is).
An important thing to consider in thermodynamics is that while thermodynamics describe the process of dissipation of a system into subsystems, there is no theory that describes the opposite, how a system comes into existence, or in technical terms, how a set of subsystems become a whole system.
When we are born, when we grow, we somehow become systems, independent and self-sustaining. This means that something new appears, a new system, with its minimum possible entropy. There's no theory that describes such behavior, it should be the counterpart of the 2nd law (entropy decreases in this conditions:...). Such whole exhibits multiple systemic behaviors that can be described as order. Order is essentially the human-subjective perception of patterns. For example, most mammals cycle between waking and sleeping. Such is a pattern we perceive, that is, such is a type of order. And such is a type of order that is lost when mammals die, among many others.
When order is lost in a system (in this case, when entropy grows), the main system dissipates into subsystems (e.g. in a decapitation, the head continues to be alive for some time, while the rest of the body is not anymore part of it). In many cases, some subsystems can continue to exist (e.g. a bone will not dissipate as fast as an eye), but in general, parts will also dissipate into subsystems, and subsystems into sub-subsystems until some point where the small subsystem is able to persist in time.
Subsystems that tend to persist in time have the possibility to join others and form new systems. For example, a dead human will dissipate usually into particles, some of them being mineral. Such mineral particles tend to persist in time, and they can later become part of other systems, like a tree.
Upon death, what is lost is the complex pattern of neural activity that gives rise to consciousness, cognition, and the sense of self. Even though the physical matter of the brain and body remains, the electrochemical signals and functional connections between neurons that encode memories, personality, and experiences are disrupted and eventually cease at death.
From a physicalist viewpoint, the mind arises from the physical processes of the brain. So when the brain can no longer sustain organized, integrating activity due to cell death and system failure, the mind is lost along with it despite the matter itself persisting.
So the loss of life and the associated subjective experiences of personhood are due to the loss of physiochemical complexity and information processing capacity - even if the raw material of the brain itself does not disappear right away. What makes "you" you is not the matter itself, but the dynamic informational processes and patterns in the brain that get destroyed upon death. So while the matter remains, the essence of the living person is no longer present.
The short and simple answer: Upon death life is lost.
More specific: The physiologic and mental processes stop in an irreversible way and the organic structures decompose.
Life seems to be an evolving pattern. Simple life can reproduce itself. Very simple forms such as viruses are not always classed as living. Intelligent life can modify itself according to what it experiences. The intelligence in the Chinese Room may be a card index, but it will continue to live as long as it is kept updated. And there may be other things that we do not yet classify was alive or not.
Consider death as a process rather than the event of an instant. A simple creature such as yeast may survive being frozen, or otherwise put into suspended animation where it is not living but it can be bought back. A virus is capable of making copies of itself when in a cell, so it has many of the characteristics of life, but outside of a cell it is just a big molecule. We can regard the suspended animation state as being neither life or death, but a hiatus between life and a possible further state of life. If the thing in suspended animation is damaged, it may not be dead but it would be soon if it were re-animated. We can freeze and recover animals as large as hamsters. No-one has yet scaled yet this up to humans.
What about the Chinese Room? If the card index is damaged by fire so it no longer works, then it is dead. If the person who ran the Chinese Room and answered the questions is dead, then it is in suspended animation, and it could be revived if a replacement was trained. Whether it is complex enough to be classed as 'alive' I don't know, but I like to think it could be if it was large enough.
We can see that the terms 'dead' and 'alive' are pretty elastic, and there is no sharp boundary between the two. Many things clearly fall into one state or the other. Dying is not instant. Machine Learning (the right term for AI today) is probably not complex enough to be called life yet, but it could be classed as living one day.
For physicalists/materialists/positivsts life has at most an epiphenomenal meaning. So death is also meaningless.
Furthermore:
because their starting assumptions are untenable. But to jump from that recognition to belief in soul IS a jump. One can say something non-material exists without reifying it to soul/God etc.
The original meaning of the word spiritual was to refer to this non-reified non-materialist outlook. Nowadays it has come to mean adherence to some new age cult.
Presumably we need a new word ...
Blessed is he that has a soul, blessed is he that has none. But woe and sorrow to him who has in himself its conception
From one of the new age fashions
Note: You need to question your juxtaposition monism-physicalism. Physicalism can never be monist because there is invariably the physicalist — hard as a nail or soft as wetware — with their physicalism.
Only idealism is compatible with monism
Before we ask what is lost when we die , we must understand what is life and what is the nature of reality. Reality is a conditioned phenomena. When we accept that I am body , body is mine , body is myself then the illusion of “I am body” arises. When death occurs the illusion gets destroyed. It no longer occurs that “I am body”. What is lost is the idea of who am I ? When we accept that I am feeling, feeling is mine , feeling is myself then the illusion of “I am feeling” arises. When death occurs the illusion gets destroyed. It no longer occurs that “I am feeling”. What is lost is the idea of who am I ? When we accept that I am perception, perception is mine , perception is myself then the illusion of “I am perception arises”. When death occurs the illusion gets destroyed. It no longer occurs that “I am perception “. What is lost is the idea of who am I ? When we accept that I am choices, choices are mine , choices are myself then the illusion of “I am choice “ arises. When death occurs the illusion gets destroyed.It no longer occurs that I am choices. What is lost is the idea of who am I ? When we accept that I am consciousness, consciousness is mine , consciousness is myself then the illusion of “I am consciousness “ arises. When death occurs the illusion gets destroyed. It no longer occurs the I am consciousness.What is lost is the idea of who am I ?
Life is the acceptance of illusion of I am body , feelings, perceptions, choices and consciousness. Death is the destruction of that illusion. It results in deep suffering if we are not mentally prepared.
Life is a combination of body , feelings, perceptions, choices and consciousness. Death is a separation of body, feelings, perceptions, choices and consciousness.
Life is a development of who am I ? Death is the loss of the idea of who am I ?
Few things, like cravings ,do not die easily and can even persist even after death.
This answer reflects some of the existing ones but tries to bring as concisely to the point as possible (to me, at least).
Dying is, like everything else concerning living matter, a chemical process with the following attributes:
Death is the point in time when certain (legal) definitions have been met. There can be different types of Death (i.e., clinical death could be defined when breathing and pulse have stopped; brain death could be defined when there is no measurable brain activity, albeit the rest of the body might still be working; and possibly other definitions).
So to answer the main question, "what is lost on death":
Some random rambling:
EDIT: addedd the answer to the titular question.
What gets lost upon death (/what you gain upon birth) (an incomplete list..):
Better question: what "remains"?
This is a useful question to ask, as it forces consideration of two problems with the physicalist characterization of life.
The first problem is that even from a physicalist POV a materialist explanation of life is clearly entirely inadequate. This is because it is not the MATTER that does the things that life functionally can do. It is instead the organization and structure of the matter that is key. Organization and structure are Logic properties, which themselves have no energy, volume, etc. These logic abstractions must be present or a living thing cannot be alive. Physicists also can only do physics with information as well, which also falls in the category of abstractions. But this is even more obvious with life. Physicalism, to explain life, ontologically cannot be monist, as it requires the existence of things that ontologically fall into the realm of abstract objects.
However, consideration of the zombie thought problem raises a further concern. If life breaks down organizationally, then a person dies — what would happen per physicalism our microsurgery skills increase dramatically and the now dead body were then modified to regain organizational self regulation etc, but just did all of this somewhat differently? Could it be possible that this revised bio-construct could function as “life” but lack a self? Lack the awareness, emotions, qualia of our now dead loved one, while motivating their now revived body? Physicalist functionalism is possible without consciousness. Dennett and the behaviorists are not wrong on this point. And if a revived body lacks a self, there WOULD be something lost in that death and revival sequence.
You are confusing physicalism with a very narrow version of materialism.
While the material in a body before and after death (assuming a quick and peaceful death for the sake of the argument) is nearly identical, there is something else physical that is not - movement, chemical reactions, biological activity.
Muscle movement, including the heart pumping blood. Oxygen exchange in the lungs, digestion, nerve impulses from the small nerves in the body to the big network in the brain. Enzyme production and cell division. Millions of small and larger processes within the body are entirely physical. At death, one by one they cease to be.
A living body and a corpse are identical only if you ignore time, if you take a snapshot and look not very closely.
What is lost upon death is the activity of the body as a system, which is why we can say that the system has ceased to be, even if the body (as a corpse) is still present. But all the processes that made up the system have come to a halt.
It's like confusing the corporate headquarters building of a company with the company itself. When the company goes bancrupt, the building is still there - but there's nothing happening inside anymore.
If something at the moment of death contains the same matter as that something when alive, what is lost?
Life is not a quantity of matter. It is physical quantities between certain boundaries. Death is at least some of those physical quantities going out of those boundaries.
There is nothing which would be alive at one moment and dead at another. If something is alive and something is dead, then they cannot possibly be the same thing.
It is presumably the case that some part of the person when alive is still there unchanged when the person just died, but this part cannot possibly be the whole of the person. No magic there.
Consciousness might be something else altogether, but this is not the subject. Wrong question?
How does physicalism (physical monism) explain what that loss is?
The question, to me, seems... kind of absurd. How do we know that someone is dead? How does, for example, an EMT or a doctor decide that a patient is dead?
They don't pray. They don't light incense and seek the answers from souls and spirits. They decide a person is dead based on physically detectable signals. Do they have a pulse? Or brain activity?
We know someone is dead first and foremost because of physical things. The physical aspect of death isn't some great mystery, it's the most immediate way we know someone is dead in the first place.
