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

Etymology The name atom comes from the Greek ἄτομος (atomos‚ "indivisible") from ἀ- (a-‚ "not") and τέμνω (temnō‚ "I cut")‚[3] which means uncuttable‚ or indivisible‚ something that cannot be divided further.[4] The concept of an atom as an indivisible component of matter was first proposed by early Indian and Greek philosophers. In the 18th and 19th centuries‚ chemists provided a physical basis for this idea by showing that certain substances could not be further broken down by chemical methods
