Temperature is a measure of the average kinetic energy of a substance. It can also be considered a relative measure of the difference of the heat content between bodies.
Heat capacity is defined as the amount of heat energy required to raise the temperature of one mole or atom of a material by one ºC without changing the state of the material. Thus, it is the ratio of the change in heat energy of a unit mass of a substance to its change in temperature. The heat capacity, often referred to as thermal capacity, is a characteristic of a material and is measured in cal/gram per ºC or Btu/lb per ºF.
