Heat is something, which produces the sensation of hotness or coldness to us. When we rub our hands, they become warm. Warm means hot. In fact, the kinetic energy of the moving hands is converted in the form of heat energy due to the friction between our hands. According to the kinetic theory of matter, the molecules of the substance have kinetic energy due to their motion. When a substance is heated, its molecule absorbs heat energy and move with higher kinetic energy. Substance having equal masses requires different amount of heat. This specific property o
