The heat capacity of liquid ethanol is 112.4 joules per kelvin for each mole of atoms. Solid ethanol has a heat capacity of 111.46 joules per kelvin, while gaseous ethanol's heat capacity varies depending on the ambient temperature.
Heat capacity, also known as thermal capacity, is a common measurement in chemical engineering and construction. It is best known to laypeople in its dietary role; the calories measured in food are a unit of heat capacity. The measure commonly called a calorie is more correctly called a kilocalorie and is the measure of the amount of heat needed to raise the temperature of 1 kilogram of water by 1 degree Celsius.
