Boyles lay question or not????

Is HELL endothermic or exothermic?


The following is an actual question given on a University of Washington
chemistry mid-term exam.


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.

Here is the "Bonus Question" on the exam:
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 are 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 (a girlfriend of mine
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 2 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."


THIS STUDENT RECEIVED THE ONLY "A."

Excellent....

Green incoming

Im not one for writing profanities but..

that was fu*king great

[jorawley]

superb.... that is getting copied and e-mailed....
green en route

Is this not a diving forum ?
Boyles law is for isothermal compression (there is no change in temperature)

Boyle's law

The students meant Charles' law

Charles's law

Of course they are both just simplifications or one unifying gas law

Ideal gas law

One can not really use the ideal gas law as the basic assumption is the size of the particles are small compared to the mean free path. The people also should not interact (bump into each other). This is probably not true in Hell (if two have to share the same cell / shake hands)

The more general van der Waals equation is then a better approximation

Van der Waals equation

Or will the hell corrections

Hell corrections to Van der Waals equations

ps do I get a green from all those that posted how funny it was ;-)

Heres another one to balance out the equation

Is Heaven hotter than Hell?

The temperatures of Heaven and of Hell are not given specifically in the Bible. That may be because the various temperature scales ~ Fahrenheit, Celsius, Rankin and Kelvin, were not created by the 1st century CE. However, there is sufficient data available to calculate the temperature of Heaven. The maximum temperature of Hell can also be determined.
Heaven's temperature:

Isaiah 30:26 states: "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."

One individual interpreted this passage as meaning that the radiation received by Heaven from the sun is 7 times 7 or 49 times as much as the earth does today. 1 Added to that is the contribution of the moon which would equal the present amount that the earth receives from the sun. Thus Heaven would receive (49 + 1) or 50 times the radiation as the earth does today.

The Stefan-Boltzmann law for radiation links the temperature of an object with the amount of radiation received. It would predict that the temperature of heaven would be 498 degrees Celsius hotter than the earth is currently. Thus heaven would be about 525 °C or 977 °F.

However, this temperature would only be the "steady-state" temperature. Presumably Heaven was created shortly after Earth so that it would be ready for its first inhabitants: Abel, Adam and Eve.

Revelation 21:17 says that the walls of New Jerusalem are 144 cubits thick. This is about 66 meters or 216 feet. Such a thick wall would be an effective insulator. Heaven would thus have taken many months to reach its equilibrium temperature. But it presumably has reached about 525 °C today.

Hell's Temperature: Revelation 21:8 states

"But the fearful, and unbelieving ... shall have their part in the lake which burneth with fire and brimstone."

Brimstone is sulphur. In order for sulphur to be molten, its temperature must be at or below 444.6 °C or 832 °F.

Thus heaven is at least 80 °C or 145 °F hotter than Hell.

Assuming that the glorified bodies that the inhabitants have in Heaven are as sensitive to heat as our present earthly bodies, then they would suffer greatly; Heaven would become worse than Hell. Since that cannot happen, due to theological considerations, Heaven must have some very effective methods of air conditioning to handle the excess incoming radiation.

are you sure sulphur is molten below the figure quoted as I remember sulphur powderfrom school and given that it was 20 deg C in the labs, using your figures it should be molten at room temp


sorry just being a pedant this morning

So your schools temperature was at or just below 444.6 °C. I know sometimes school was hell but.....
