## Is Hell Endothermic or Exothermic?

Dr. Schlambaugh, a senior lecturer at the Chemical Engineering Department,University of Oklahoma, is known for posing questions on final exams like: "Why do airplanes fly?" In May a few years ago, the "Momentum, Heat and Mass Transfer " exam paper contained the question: "Is Hell exothermic or endothermic? Support your answer with proof." Most students wrote proofs of their beliefs using Boyle's Law or similar. One student, however, wrote the following: First, we must postulate that if souls exist, they must have some mass. If they do, then a mole of souls also must 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 does 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 religions say that if you
are not a member of their religion, you will go to Hell. more...

paper contained the question:
Most students wrote proofs of their beliefs using Boyle's Law or
similar. One student, however, wrote the following:
First, we must postulate that if souls exist, they must have some mass.
If they do, then a mole of souls also must 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 does not leave.
Therefore, no souls are leaving.

## Is hell exothermic or endothermic? Support your answer with a proof.

A true story. A thermodynamics professor had written a take home exam for his graduate students. It had one question:

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 more...

## Final Exam

A retiring Phys Chem professor was setting his last exam, for a graduate course in statistical thermodynamics. Being a bit bored with it all, and with a well-kept and wry sense of humor, he set a single question on the sheet: "Is Hell endothermic or exothermic? Support your answer with proof."
He had little idea what to expect, or how to grade the results, but decided to reward any student who was able to come up with a reasonable and consistent reply to his query. One A was awarded. Most of the students wrote proofs of their beliefs using Boyle's Law or some variant. The top 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 more...

## Theory on Hell

The following is an actual question given on a University of Washington chemistry mid-term exam paper:
"Is Hell exothermic (gives off heat), or endothermic (absorbs heat)? Support your answer with a proof." Most of the students wrote proofs of their beliefs using Boyle's Law (gas cools off when it expands and heats up when it is compressed) or some variant thereof.
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. 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. 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 since people do more...
