Still shot from the movie Schindler's List The photo above shows Ralph Fiennes as Amon Goeth, shooting prisoners in the Plaszow camp in the movie Schindler's List. In the background is the quarry where Steven Spielberg built a replica of the Plaszow camp.
Thermal energy is the total kinetic and potential energy of the  particles in a substance.    related to the motion of molecules   . Thermal energy. The amount of heat energy in an object depends on three things :  it's temperature, it's mass, and the material it's made from.
where k is the Boltzmann constant. The total thermal energy of a sample of matter or a thermodynamic system is consequently the average sum of the kinetic energies of all particles in the system. Thus, for a system of N particles its thermal energy is.hermal energy is the portion of the thermodynamic or internal energy of a system that is responsible for the temperature of the system. The thermal energy of a system scales with its size and is therefore an extensive property.
