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 mass. If they do, then a mole of souls can 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 to hell, it will 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 of these religions state that if you are not a member of their religion, then 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 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 the souls and volume needs to stay constant.
Two options exist:
Thus hell is exothermic.
The student, Tim Graham, got the only A in the class.
