The study of heat relate to Kinetic theory of matter is that universe is made up of matter and energy. Matter is made up of atoms and molecules. Atoms and molecules are always in motion because energy. Energy forces them to contact into each other or vibrate back and forth. When this happens molecules and atoms creates a form of energy called (heat) thermal energy‚ which is present in all matter. (“Matter”2009) Molecules interact‚ attracting each other
