When a substance is hotter it has more energy then a substance that is cooler thermal energy is found in the state for example:gas has more energy in the gas state then the solid state,All molecules contain some amount of kinetic energy, that is to say, they have some intrinsic motion. ... Thus, the heat of an object is the total energy of all the molecular motion inside that object. Temperature, on the other hand, is a measure of the average heat or thermal energy of the molecules in a substance.
