Subject: Exothermic or endothermic?

The following is an actual question given on a University ofWashington Chemistry mid-term. The answer by one student was so "profound" that the professor shared it with colleagues, via the Internet, which is, of course, why we now have the pleasure of enjoying it as well:

Bonus Question: Is Hell exothermic (gives off heat) or endothermic> (absorbs heat)
> Most of the students wrote proofs of their beliefs using Boyle's Law
> (gas cools when it expands and heats when it is compressed) or some
> variant.
> 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. Most of these
> religions state that if you are not a member of their religion, you
> will go to Hell.
> Since there is more than one of these religions and since people do
> not belong to more than one religion, we can project that 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 of the volume in Hell because
> Boyle's Law states that in order for the temperature and pressure in
> Hell to stay the same, the volume of Hell has to expand
> proportionately as souls are added.
> This gives two possibilities:
> 1. 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. 2. If Hell is expanding at a rate faster
> than the increase of souls in Hell, then the temperature and pressure
> will drop until Hell freezes over.
> So which is it?
> If we accept the postulate given to me by Teresa during my Freshman
> year that, "It will be a cold day in Hell before I sleep with you,"
> and take into account the fact that I slept with her last night, then
> number two must be true, and thus I am sure that Hell is exothermic
> and has already frozen over. The corollary of this theory is that
> since Hell has frozen over, it follows that it is not accepting any
> more souls and is therefore, extinct......leaving only Heaven,
> thereby proving the existence of a divine being which explains why,
> last night, Teresa kept shouting "Oh my God!"

It's brilliant! I wonder if it really is true's too good to come from our current university educational system. Thus, how could it be shared??? :-)

Brilliant student! He should have been given his degreee immediately based on this paper!

True or not, it is a great story, but one I have heard years ago.

Thanks for stopping by my blog. I had read this before but loved to be reminded.
