C in heat equation
WebHeat Capacity . The heat capacity of a substance is defined as the amount of heat it takes to raise the temperature of a substance by 1°C. In equation form, this can be represented as the following: or . Note: You can determine the above equation from the units of Capacity (energy/temperature).
