Is Hell exothermic or endothermic?

A kid proved that Hell cannot exist. Incredible. Now where am I going to damn people to? Utah?

The following is supposedly an actual question given on a University
of Washington chemistry mid-term. The answer to the bonus question
by one student was so "profound" that the professor shared it with
colleagues, via the Internet, which is, of course, why we now have
the pleasure of enjoying it as well.

Bonus Question: Is Hell exothermic (gives off heat) or endothermic
(absorbs heat)?

Most of the students wrote proofs of their beliefs using Boyle's Law
(gas cools when it expands and heats when it is compressed) or some variant.

One student, however, wrote the following:

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 Teresa during my Freshman
year 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 existence of a divine being which explains why, last night, Teresa kept shouting
"Oh my God."
