Hell question

The following is an actual question
given on a University of
Washington engineering mid-term.
The answer was so "profound" that
the Professor shared it with
colleagues, and the sharing
obviously hasn't ceased...
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 off 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 that souls
are moving into Hell and the rate
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 us look at the different
religions that exist in the world
today. Some of these religions state
that if you are not a member of
their religion, you will go to Hell.
Since there are 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 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. Of course, 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 Banyan 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 still have not succeeded in
having sexual relations with her,
then, #2 cannot be true, and thus I
am sure that Hell is exothermic and
will not freeze."
