Which statement best describes temperature? A. It is a measure of heat flow. B. It is a measure of average kinetic energy. C. It is a measure of average potential energy. D. It is a measure of average potential and kinetic energy. E. It is a measure of radiant energy.

Temperature is a measure of average kinetic energy. temperature and kinetic energy are directly proportional which means when kinetic energy of a substance increases, temperature increases. Temperature is the measure of hotness of coldness of a substance. The answer is B>.
