Is hell exothermic or endothermic???

IS HELL EXOTHERMIC OR ENDOTHERMIC???

The following is an actual question given on a University of Washington chemistry mid-term. The answer was so "profound"
that the professor shared it with colleagues, which is why we now have the pleasure of enjoying it as well.

Quote:
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 off when it expands and heats up 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 that souls are moving into Hell and the rate 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. 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 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 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. Of course, 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 Ms. Teresa Banyan 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 still have not succeeded in having sexual relations with her, then, #2 cannot be true and thus I am sure that Hell is exothermic and will not freeze.

This student received the only "A" given.

Credit goes to siddarth from another board i visit.

LOL :lol: WTF?? thats all i can say for that

that's an extremely well thought out response, very good :)

i'm going to share this around with some of my friends and a few...nicer teachers...:D

A 20 mark philosophy question for UNI
Define bravery:

Answer given: This is

But in real life this guy failed

the strange thing is I actually understood the whole lot of that I think it was well written and used all subject matter requied to recieve an "A".. I would have given him the sasme mark..

Also I heard of a story about a student that had a essay to do and the question was something about

"Why do you think "blah blah blah" happens"

he answered : Why not

That was philosophy as well and he recieved an "A"..

he worded the answer very well hehe

and in regards to the philosophy, those words "Why Not?" can mean a helluva lot ;)

Hahaha, funny shit!

Note "Bonus Question" the A shouldnt only be on this question

bonus question = bonus marks which got him the A ???

lol yeah woops... My typeing isn't the greatest :p..

my particular favourite exam answer was in chemistry, and if i recall, the question was something like this:

Fe + HCl -> Au + ?

my answer to this question:

Congratulations sir, you appear to have found the philosophers stone.

i got full marks for the question, nobody else in the class answered it, or said it was wrong muaha.

lol
Im also verysure HCl (compound) dosnt exist. If u want to bug the marker on this as well
Its H+ and Cl- ions in aqueous form

HCl can exist in gaseous form.

don't understand where you are coming from Vinc, HCl is Hydrochloric Acid....

Alright u forced me into this argument:

HCl(aq) is hydrochloric acid meaning
H+(g) Cl-(g) + H2O(l) -> H3O+(aq) + Cl-(aq)
this is not an equilibrium due to the strength of Cl- and the weakness of H3O+

<> in my representation = equilibrium

I’m very sure in even gas terms there is a complete electron transfer
H + Cl -> H+ + Cl- and these atoms hang around each other because of opposite charges not because of chemical bonding - hence the gas form
If it was a proper bond the strong intermolecular dipole forces like in NaCl (where there isn’t a complete electron transfer) would form a crystal (salt) and not a gas. I might add that to my knowledge there is no proof either way only speculation and reasoning.

It is referred to as a compound as to not confuse people and make equations easier to understand. Chemistry has a funny way of destroying previous concepts with new ones as a way of teaching.

For example. Using the most common Iron ion 3+ instead of the rarer 2+
Fe(3+)(s) + 3Cl-(aq) + 3H3O+(aq) <> FeCl3(aq) + 1.5H2(g) + 1.5H2O(l)

instead of the more basic Fe + 3HCl -> 1.5H2 + FeCl3

I’m not all sure about the FeCl3(aq) if its an aq or s ill need to check the solubility rules

One good test to see how good your teacher is to ask if pure water conducts electricity.
The correct answer is yes
2H2O <> H30+ + HO-
water self dissociates to form a week acid and base
These ions can now transfer electricity, though be it a very very small amount.

Note: I haven’t even looked at a chem. book in 9 months since final exams
Also please correct me if I need it :)

meanwhile, back in the real world... :wink:

HCl am Covalent

This is another misconception thats taught, to make chem easier to understand. Supposivly non metals + non metals = covalent, but:

First of all there are scales to ionc bonding and covalent bonding. This has to do with electro negitivity. The more difference in electro negativity the more ionic the bond. The only pure covalent compounts possible are molecules, such as H2 S8 ect were the isnt a difference in electro negativity because they are the same types of elements.

There for HCl if it were to exist in a compound would be very ionic and partially covalent due to significant difference in electronegativity.

Also hydrogen is unusual as it can take on or drop off electrons with ease.

In a normal bonding the electrons are shared but the chlorine atom is so much larger and has so many more protons it just takes the electron without shareing it. Hence electron transfer

dang..... :shock:

OK... here we go...

As I said before, HCl can exist in gaseous form. Heck, they even sell plants for the production of HCl gas places like here .

Also, to Neo's point of HCl being covalent, he's right it is considered to be covalent, due to the H-Cl bond possessing a low ionic character.

Chemical bonds are almost always a mixture of both ionic and covalent type bonding, with shared electrons spending disproportionate times orbiting the atoms which they bind. Bonds are classified as ionic or covalent based on their percentage ionic character, which is explained here using HCl as an example.

Hope this information helps.

End chembabble.

ok i wasn't trying to force you into the argument...but i just wanted you to clarify it for me thanks btw :) i wasn't sure what you meant when you said that HCl wasn't a compound....

anyways, you and unscarred have both fixed that for me :)

consider that I'm reaching back almost 8 years for this info before you toast me :P but the reasoning that HCl isn't a true compound is that if something is a compound, it implies a strong molecular bonding between all the components in the compound - hence why most compounds are made up of similarly massed elements

pure water wont dissociate.. cos its not conducting electricity.

you say that the electricity breaks down the water molecules and forms a weak acid.... which conducts electricity. but in fact that it needs to conduct FIRST to break it down.

pure water is an insulator.

impurities allow electricity to flow which then enables the acid to form.

ahh, perhaps, but electricity is simply the flow of electrons, and starting out as an insulator, water will take a small amount of capacitive charge, which injects extra electrons into the water, thus fragging with the ionic balance in the water molecules or some such crap *grin*

enough voltage and pretty well nothing is an insulator

i agree
