"so, at this college there was an extra credit question "Is hell endothermic or exothermic." this is what one kid wrote:

First, we postulate that if souls exist, then they must have some mass.
If they do, then a mole of souls can also have a mass. So, at what rate are souls moving
into hell and at what rate are souls 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 souls entering hell, lets 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 people do not
belong to more than one religion, we can project that all people and 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 in volume in hell. Boyle's Law states that in order
for the temperature and pressure in hell to stay the same, the ratio of the mass of souls
and volume needs to stay constant.

So, 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 (i.e.,Hell
is exothermic).

Of course, if hell is expanding at a rate faster than the increase of souls in hell, than
the temperature and pressure will drop until hell freezes over (i.e.,Hell is endothermic).
So which is it? If we accept the postulate given by Ms. Therese Banyan during my freshman
year, "That it will be a cold night in hell before I go out with you," and take into
account the fact that I still have not succeeded in having a relationship with her, the
second case cannot be true. Therefore, hell is exothermic.
