Of course this subject is in figurative form, whether hell exists or not is a subject to be discussed by the religious, and whoever has been, I hope that he doesn't come back to tell us about this place so feared by humanity. However, we can make an analysis of hell basing ourselves on the concept of endothermic and exothermic processes. But first a definition of the different types of reaction to heat:
Endothermic Process: is one that occurs with heat absorption.
Exothermic Process: is one that occurs with the release of heat.
Now a question: at what rate do souls move in and out of hell? We will ignore the answer, taking the following position: once a soul enters the abyss it never leaves, despite some religions claiming otherwise. Therefore, there are several predictions for souls going to hell, with each belief defending its position.
For example, some religions assume that it is the only rule of faith, so if you don't follow the principles it preaches, you will go into darkness rather than light. Assuming then that almost everyone was going to burn in the “marble of hell”, what would this place look like? If there are no souls leaving and with death rates increasing at an accelerated pace, what can be expected is a terrifying increase in the doomed souls, that is, an overpopulation of hell.
According to the boyle's law and its fundamental principle: Under constant temperature, the product of pressure and volume of a gaseous mass is constant, being thus, for the temperature and pressure in hell to be the same, the ratio between the mass of souls and the volume of hell must be constant.
Following this reasoning, we then have two options: Imagine if the rate of souls that are sent daily to the Lucifer is greater than the expansion rate of hell, then an explosion will occur, due to the increase in temperature and pressure. Now if hell undergoes an expansion greater than the entrance of souls, exactly the opposite will occur, the pressure and temperature will be so minimal that hell will freeze.
Returning to the initial question: Is hell endothermic or exothermic? Taking into account everything that has been proposed about hell, it is easier to believe that it is exothermic and that the temperature and pressure increase more and more: it is a real fire that burns without cease!
