Highest possible temperature = Planck temperature?

[Lisa...]

Hey there!

Today I've had a discussion with my professor on the existence of a so called highest possible temperature. I've read somewhere that this is called the Planck temperature, but my teacher believes an object can be heaten to an infinitely high temperature and he was very sure of his case.
I must say he loved to humiliate me in front of the whole class and I do feel very bad about it, so I just wanted to know what do you guys think?

It is interesting that infinite temperatures are not ruled out by the theory of thermodynamics, but it is also interesting that it is not possible to heat a body to an infinite temperature. In order to heat a body you need a hotter body - which is not possible when you reach infinite temperatures.

Did your professor really say that, or did he say that an object can be heated to any temperature, no matter how high? Those are different statements- there is no such thing as "infinitely high temperature".

He literally said: 'An object can be heaten to an infinitely high temperature', just as I wrote.
