What does the potential energy in liquid have to do with the formula Ek
T, since that's the formula for kinetic energy and not total energy?
Also, according to DevaDevil in this link: http://www.chemicalforums.com/index.php?topic=46364.msg175807#msg175807
Molecules in ice and liquid water have the same kinetic energy at the same temperature because of Ek
T. So to set this straight, is it then that molecules in ice and liquid water at the same temperature have the same kinetic energy but molecules of liquid and molecules of gas (or molecules of solid and molecules of gas) at the same temperature have different kinetic energies then?
Sorry but I also have a question about when you said the potential energy of a gas is zero. I see how the logic works, but in the same link above rabolisk had said that molecules of liquids have more potential energy than molecules of solids. So is the gas just different again in this case too, and in increasing order of potential energy, it goes gas<solid<liquid?
