Is hell exothermic or endothermic? What Says Snopes.com?

Extract from Snopes.com

"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 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 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, than the temperature and pressure will drop until hell freezes over."

 

Claim: A student came up with a clever proof and pithy saying in response to an exam question about the physical properties of Hell.

FALSE

Variations:

• Commonly, the piece begins with a statement meant to authenticate the story. "An actual question given on University of Washington chemistry midterm," "from a Yale professor," and "Dr. Schambaugh, of the University of Oklahoma School of Chemical Engineering, Final Exam question for May of 1997" have been spotted so far.
• Sometimes the student's comments culminate in the assertion that hell must be exothermic because a girl he'd been chasing had sworn it'd be a cold day in hell before she'd sleep with him, and he'd so far been unable to get to first base with her.
• Often the story concludes with "The student received the only 'A' given on the exam."
