Does Hell Really Exist?

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 using Boyle's Law or some variant. One student, however, wrote the following:

First, we potulate 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 goes into hell, it will not leave. Therefore, souls are not 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 this 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 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 of 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 faster rate than the increase of souls in hell, than the temperature and pressure will drop until hell freezes over.
