Physcial Properties of Hell

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.

It was not revealed what grade the student got.

The temperature of Heaven can be rather accurately computed. Our authority is the Bible: Isaiah 30:26 reads, "Moreover, the light of the Moon shall be as the light of the Sun and the light of the Sun shall be sevenfold, as the light of seven days." Thus Heaven receives from the Moon as much radiation as we do from the Sun, and in addition 7 times 7 (49) times as much as the Earth does from the Sun, or 50 times in all. The light we receive from the Moon is 1/10,000 of the light we receive from the Sun, so we can ignore that. With these figures we can compute the temperature of Heaven.
The radiation falling on Heaven will heat it to the point where the heat lost by radiation is just equal to the heat received by radiation, i.e., Heaven loses 50 times as much heat as the Earth by radiation. Using the Stefan-Boltzmann law for radiation,


(H/E)^4 = 50

where E is the absolute temperature of the earth (300K),
gives H, the temperature of Heaven, as 798K (525 C).
The exact temperature of Hell cannot be computed ... [However] Revelations 21:8 says "But the fearful, and unbelieving ... shall have their part in the lake which burneth with fire and brimstone." A lake of molten brimstone (or sulphur) means that its temperature must be at or below the boiling point, 444.6 C.

We have, then, that Heaven, at 525 C is hotter than Hell at 445 C.

Heheh, that first one's on my physics professor's wall.

I get the second one, but I'm not sure why the first one's funny, unless it's all dependent on the fact that he managed to fit in references to "all hell breaking loose" and "hell freezing over"

Last night i slept with Jane Doe, who told me in first year "Hell will freeze over before i sleep with you" and so with that in mind i conclude that Hell is expanding faster and is therefore endothermic

Blue for the full joke.
