- 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
- 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, let's 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, then the temperature and pressure will drop until Hell
- freezes over.
