The amount of heat needed to increase the temperature of a certain mass of a substance by 1°C is called its specific heat capacity. Specific heat capacity is a material property that indicates how much heat energy must be supplied to raise the temperature of 1 kilogram of a substance by 1 degree Celsius. It is usually denoted by the symbol ccc and is measured in joules per kilogram per degree Celsius (J/kg°C) or joules per kilogram per kelvin (J/kg·K).
