From this Chapter we will study thermal properties of matter, that is what means the terms “hot” or “cold”, what is the difference between “heat” and “temparature”, and the laws relative to these concepts. We will know that the thermal phenomena are determined by internal motions of molecules inside a matter. There exists a form of energy which is called thermal energy, or “heat”, which is the total energy of all molecular motions, or internal energy. | GENERAL PHYSICS II Electromagnetism Thermal Physics 4 22 2008 1 Chapter XIV Kinetic-molecular theory of gases -Distribution functions 1.

We will know that the thermal phenomena are determined by internal motions of molecules inside a matter. There exists a form of energy which is called thermal energy or heat which is the total energy of all molecular motions or internal energy. To find thermal laws one must connect the properties of molecular motions microscopic properties with the macroscopic thermal properties of matter temperature pressure . . First we consideran modelization of gas ideal gas . 4 22 2008
