A Good Question: Is Hell Exothermic Or Endothermic?
The following is supposedly an actual question given
on a University of Washington chemistry mid-term

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 Jessica
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, Jessica kept shouting
"Oh my God!"
