Hell explained
The following is an actual question given on a  University  of Arizona
  chemistry mid term, and an actual answer turned in by a student.

 The answer by one student was so 'profound' that the professor shared
 it with colleagues, via the Internet, which is, of course, why we now
 have the pleasure of enjoying it as well :
 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, which is unlikely.. 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 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 two 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.'
