Hi.
In all of my question, I mean degrees celsius when I say degree.
Think we have a 0 degree ice. we give some energy to it (by a heater) and all of it get into a 0 degree water.
How does the kinetic and potential energy of the molecules change?
In the book in which I saw this question, it said that potential energy increases and kinetic energy of molecules doesn't change because of K= 3/2 k T. My problem is that we use K = 3/2 k T in ideal gases. is it valid for liquids or solids? Is it right to say that the mean kinetic energy of a solid and a liquid (of the same material and the same mass) is constant in temperature Θ? It doesn't seem logical. If it is true, how the water is more fluid and free than a solid?
Whatever the answer is, is it same for liquid and gas?
Sorry for my English.
