Maximum temperature?

I suppose that would make it the largest meaningful temperature.

I think we have a winner here. The key word here is, of course, 'meaningful,' energy isn't really created so after 1 Planck second, you're talking about the smallest internval of time that is meaningful.

Hah, I dont see a winner . The problem with using that as a standerd for maximum temperature is it has all the atoms included, However it is possible to convert that large mass into large amounts of energy and converting that energy into thermal energy. So I say it would be higher then that even. How high? How much mass is there in the universe, Then use E=mc2 and figure it out.

Maximum Temp?

Off-hand, I'd say it's infinite. If it wasn't, it would mean that black holes could even eventually reach a maximum energy limit. Interesting question.

Particles (with mass) can't reach the speed of light that requires infinite energy. This has already been pretty well covered here so I won't waste anyone's time with the details, but accelerating an electron to the speed of light requires more energy than there is in the universe.

Actually, there's some theories now that are possibly revising that. One, which involves the "Higgs field" says that if enough energy (super massive amounts) is applied to a system, even mass could have little meaning. Pretty interesting stuff.

One of Brian Greene's books goes into more detail about it, I think it's called "Fabric of the Cosmos."

Hottest temperature? That would be the temperature of the singularity from which the big bang originated from. Can't have more energy than what you started with.

If we have a gas at 0 degrees celsius and for every degree rise in temperature, the volume of the gas increases by (1/273) the orignal volume of the gas. This is called as Charles law( I think so) and is only applicable for gases.


The new volume = [vol.of gas at 0 deg. + (vol.of gas at 0 deg* the desired temperature/273]

Gives us a rough idea about expnasion due to heat......

That requires a constant pressure.

this reminds me of the question"

could god microwave a burrito so hot that even he could not eat it?
