Is it true that it can get colder than absolute zero?
If so, HOW?
Is there any limit to cold? Or hot?

answers:
Clive say: Which part of "absolute" are you having difficulty with?
-
james say: There is no known way at present to do this. This does not mean it can not be done.
-
PhotonX say: Absolute zero is, by definition, the coldest possible temperature.
.
If only there were some way of looking up the meaning of words, huh?

Donut Tim say: No, it is not true.
Temperature is a measure of energy. The least amount of energy possible is zero.
-
Ronald 7 say: No
- 273 C Is Absolute Zero Kelvin
It is the Temperature that the lightest element, Hydrogen freezes
In the Laboratory the Lowest they have gotten to has made Hydrogen Boil
For heat though the scale is infinite, the centre of stars can be Billions of Degrees C

martin say: If even electrons stop moving around an atomic nucleus, that would be colder than absolute zero.

Julien say: No, it would make no sense.
It would correspond to things like complex imaginary particle speeds or infinite density of infinitely high-energy states.
But you can have situations in which the temperature is just *undefined*, in which you can't send your system to the thermodynamic limit.

Pat Flan say: No it is not true. Absolute zero is where there is no kinetic energy between any molecule. So if temperature measures avg kinetic energy, it would be at -273 degrees C to be absolute 0.

Sammy say: What we "know" is not fact. It's just a knowledgeable guess at what we have encountered.

What we have not encountered or can't imagine, could as is very possible.

So I would suspect that we, as humans, have a very limited knowledge base.
