The absolute scale of temperature based on the internal energies of the material. 6 of 8 What is thermal Equilibrium? When two or more materials are able to transfer energy between each other but there is no net movement of thermal energy. 7 of 8 Define Temperature. The sum of the average kinetic energies of a material. 8 of 8
