Hell: Exothermic or Endothermic?

First, we need to know how the mass of Hell is changing in time. So
we need to know the rate at which souls are moving into Hell and the
rate at which they are leaving. I think that we can safely assume that
once a soul gets to Hell, it will not leave. Therefore, no souls are
leaving.
As for how many souls are entering Hell, let's look at the
different religions that exist in the world today. Most of these
religions state that if you are not a member of their religion, you will
go to Hell. Since there is more than one of these religions and since
people do not belong to more than one religion, we can project that all
souls go to Hell.
With birth and death rates as they are, we can expect the number of
souls in Hell to increase exponentially. Now, we look at the rate of
change of the volume in Hell because Boyle's Law states that in order
for the temperature and pressure in Hell to stay the same, the volume of
Hell has to expand proportionately as souls are added.
This gives two possibilities:
1. If Hell is expanding at a slower rate than the rate at which souls
enter Hell, then the temperature and pressure in Hell will increase
until all Hell breaks loose.
2. If Hell is expanding at a rate faster than the increase of souls in
Hell, then the temperature and pressure will drop until Hell freezes
over.
So which is it?
If we accept the postulate given to me by squinney one day last week when she was pissed off that, " it will be a cold day in Hell before I sleep with you, and take into account the fact that I slept with her last night, then number 2 must be true, and thus I am sure that Hell is exothermic and has already frozen over. The corollary of this theory is that since Hell has frozen over, it follows that it is not accepting any more souls and is therefore, extinct...leaving only Heaven thereby proving the existance of a devine being which explains why, last night, squinney kept shouting "Oh my God."
