A true story. A thermodynamics professor had written a
take home exam for his graduate students. It had one question:
"Is hell exothermic or endothermic? Support your answer
with a proof."
Most of the students wrote proofs of their beliefs using Boyle's Law
or some variant. One student, however wrote the following:
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. 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.
