What is the upper limit of temperature?

Question

To the point where temperature becomes meaningless?

Answer 1

That would be the Planck temperature, which is about 1.4 X 10^32 K. The known laws of physics fundamentally break down at that temperature. Extrapolating from what is known, though, space-time may dissolve into a bubbling broth of tiny rapidly forming and decaying black holes.

Answer 2

It depends a little bit on what you mean by "temperature", but there is a theoretical limit at which the energies are so high that atomic nuclei themselves dissociate; that is, their motion is so energetic that the collisional energies are greater than the atomic forces binding the nuclei. At that point, you don't even have conventional matter anymore and have more or less reverted to the early conditions in the Universe at the time of the Big Bang. That temperature is about 100 billion Kelvins.

Answer 3

theoretically the maximum temperature is where the average velocity is the speed of light this temperature is so high it's not going to be reached for awhile i haven't memorized the velocity to temperature equation so i don't know the exact temperature

Answer 4

There is a bit of debate about this, but its very very high like a number with 32 zeros on the end.

Answer 5

Upto which in one can be alive!
