Physics of Death: Where does the energy in your body go if you die one day?

In fact, we think that the energy that powers our bodies is entirely ours. According to this logic, the energy that has accumulated in our bodies should also disappear when we die. However, at this point, science We do not own the energy, but the energy owns us. expresses.

“How?” If you are one of those who say: What happens to the energy in our body after death? Let’s clarify the question.

Currently, the human body consists of matter and energy.

Energy

This energy in our body are both electrical (signals and impulses) and chemical (reactions). The same actually applies to plants, which enable the production of energy from sunlight and are supported by the process of photosynthesis.

But energy production process in humans It’s much more complex. For example, imagine that 20 watts of energy are flowing through your body at any given time, enough to power a light bulb.

This energy is obtained in many different ways and most of the time Get it from foods that provide chemical energy It is possible. The chemical energy is then converted into kinetic energy and used to power the muscles.

As we are well known from thermodynamics, energy cannot be created or destroyed. It just changes situations.

Energy

Again, the total amount of energy in an isolated system cannot change. Thanks to Einstein, matter and energy are, so to speak, two steps of the same ladder We can say that this is so.

The universe as a whole is closed, but the human body and other ecosystems are open systems. In other words: we can exchange energy with our environment. Can extract energy through chemical processes, by removing waste or radiating heat We can lose.

Let’s talk about what happens to the energy in the body after death.

After a person dies, the energy in his body goes to the environment, where the energy of all organisms goes after death. The energy stored in a person’s body when he dies It is released as heat and is harmful to creatures (worms, bacteria, etc.) and plants that eat us when we are buried. is transferred. When the body is burned, this energy is released in the form of heat and light.

When we eat dead animals or plants, We consume their energy and, in a sense, transform it for our own use. Food is metabolized as it is digested; Chemical reactions release the energy needed for living things to live, move and reproduce. This energy exists in the form of heat energy and chemical energy.

While it is true that metabolic processes in humans and other organisms produce very low-level electrical currents, their production stops when the organism dies.

Dead

The electric current stops because the energy source disappears. This situation can be thought of as a light bulb going out when the electricity is turned off. It takes years before the energy left behind by a deceased person returns to the environment as nourishment, in a sense. The remaining energy disappears shortly after death and it would not be possible to find it even after years.
