Thermodynamics Professor Robert Schambaugh of the University of Oklahoma School of Chemical Engineering had written a take-home exam for his graduate students. Dr. Schambaugh is known for asking questions such as, "Why do airplanes fly?" on his final exams. The final for Spring Semester 1997 was no different. It contained only 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, 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, 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 to the volume must remain constant.


1) 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.
2) 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.

So which is it? If we accept the postulate given me by Therese Banyan during freshman year ("It will be a cold night in hell before I sleep with you"), and take into account the fact that I still have not succeeded in having sexual relations with her, then #2 cannot be true, and therefore hell must be exothermic.

The student, Tim Graham, got the only A.
