Molar heat capacity is the thermal energy needed to raise the heat level of one mole of matter by 1 degree Celsius. The formula is written as joules divided by moles per Celsius degrees. The temperature can also be expressed as degrees Kelvin.
Heat capacity, also known as thermal capacity, is the ratio of temperature change caused by adding heat or taking it away from an object. Heat capacity is a property of all matter and is in proportion to the total size of the system. The term heat capacity originated in the 1750s, when scientists thought of heat as an invisible fluid. They believed that bodies could hold a certain amount of heat.
