This is forwarded from a graduate of the University of Oklahoma School of Chemical Engineering Dept., citing one of Dr. Schlambaugh's test questions for his final exam of 1997.

Dr. Schlambaugh is known for asking questions on his final like, "Why do airplanes fly?"

In May 1997, The Momentum, Heat, And Mass Transfer II final exam question was, "Is Hell exothermic or endothermic? Support your answer with proof."

Most of the students wrote proof 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 must also have 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 into hell, it does not leave. Therefore, no souls are leaving.

As for souls entering Hell, let's look at the different religions in the world that exist today. Some religions say 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 the birth and death rates what they are, we can expect the number of souls in Hell to increase exponentially. Now we look at the rate of change in the volume of 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 the souls and volume needs to stay constant.

Answer 1: So if Hell is expanding at a slower rate than the rate at which souls enter Hell, then the temperature and pressure will increase until all Hell breaks loose.

Answer 2: Of course if Hell is expanding at a rate faster than the increase in souls in Hell, the temperature and pressure in Hell will drop until hell freezes over.

So which is it? If we except the postulate given to me by Theresa Banyan during freshman year, that "It'll be a cold day in Hell before I sleep with you." and taking into account that I still have not succeeded in having sexual relations with her, then Answer 2 cannot be true.......thus Hell is exothermic."

The student, Tim Graham, got the only A.
