Is Hell Exothermic or Endothermic?

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

Bonus Question: Is Hell Exothermic (gives off heat) or
Endoth ermic (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 mor e 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."
