Huh? What is absolute zero in degrees celsius?

And I don't think so. I'm no physics expert though.

From what I remember of high school chemistry, there isn't one. Things just keep getting hotter.

Wow I didn't know there was a "lowest temperature possible", but it makes sense.

No, in theory there isn't. Absolute zero is when molecules are completely motionless. "Absolute hot" would be when they're moving and bumping into each other at infinite speed.

Boogie said:Umm, technically, you've got it backwards. The molecules don't stop moving because it's too cold, it's cold because the molecules stop moving
And they stop moving because there is no "energy" affecting them? Did I get it right? Do I get a star?
You're probably right. Now I am curious as to what caused the molecules to slow down entirely. I haven't taken chemistry and stuff for a very long time nowBoogie said:Umm, technically, you've got it backwards.

Well, actually, I believe that absolute zero has never been reached, it's more of a theoretical limit rather than one that has been observed.

Manics said:Yes in fact. The opposite of absolute zero is absolutely hot. Here is an example:
Looks like a dude, bad taste.

Uhh no you didn't.

If I remember right, it's the loss of kinetic energy that causes the molecules to slow down and the matter loses heat. Either you have heat, or you have an absence of heat. It's been a while since Physical Chemistry :/. However, Boogie is correct - absolute zero is a theoretical limit. Nothing (afaik) has been artificially cooled to that temperature.

That's Charlize?? WTF I didn't recognize her! She's A+ in my book, I just don't like that particular pic I guess.

Yeah, as was said, basically a lack of energy- a lack of anything to keep them moving I guess. Temperature is determined by the speed of molecule movement.NetMapel said:You're probably right.

Haha this thread took a nice detour.

Wow man, you need glasses.
That's actually not quite true. Absolute zero is the temperature at which no useful work may be extracted from the system. There is still some degree of motion which is required to maintain molecular structure, AFAIK.NetMapel said:
As for an upper limit on temperature, there IS such a thing for molecules -- at some point, the atoms become too energetic to remain bound. For individual particles, there is also an upper energy limit to their existence as well. In classic Big Bang theory, for example, there is some short interval after the creation of the universe when it was actually too hot for photons to exist.
As for the "no particle can reach the speed of light," that is patently false. Massless particles can and do travel at the speed of light.

Absolute zero is the point at which molecules stop moving you can go colder than that. 0° C is the freezing point of water but you can go colder than 0° C.
Same thing here it is possible to go to absolute zero - 1. Just a absolute zero the molecules will have stopped moving.

Its almost impossible to get to absolute zero. It gets expnentially harder the closer we get to 0K

Oh I agree (not like I have much to disagree with) but, I'm sure there is somewhere someplace in nature where this is possible.
But ... but ... it's a wave!Hitokage said:
Actually, any massless particle can move at the speed of light. Gravitons and gluons would qualify I believe. Neutrinos, while not entirely massless (although one of the flavours may actually be massless ... I'm going on memory here), basically move at the speed of light. It's something like 0.999999c or whatever.

To elaborate on Olimario's highly informative post, check out this wikipedia article about it:

Thank you I feel much more informed. That was a good primer.

*sigh*
I guess it's my own fault for choosing this username, but I am not Olimario. My real name starts with O - hence TheOMan. I'm seriously considering changing my handle to avoid the confusion.
*shakes fist at Olimario* Heh. Oh and yeah, you're welcome.
Also, did jinx get banned??? Buh??

Yeah, I meant Jinx, because his and oli's avatars are really similar. And I didn't sleep much. And all sorts of other excuses that don't involve me admitting I made a mistake.
After I started this thread, I thought I ought to discourage people from similar displays of cynicism.Boogie said:
