Heat capacity
Heat Capacity
Heat capacity or thermal capacity (pronounced: /hiːt kəˈpasɪti/) is a physical property of matter, defined as the amount of heat to be supplied to a given mass of a material to produce a unit change in its temperature. The SI unit of heat capacity is joule per kelvin (J/K).
Etymology
The term "heat capacity" was first used in the early 19th century by French physicist Pierre Louis Dulong and French chemist Alexis Thérèse Petit. The term is derived from the Latin calor which means heat and the Latin capacitas which means capacity.
