What is Heat Capacity?

Heat capacity is the amount of heat energy required to raise the temperature of a substance by one degree (Celsius or Kelvin). Specific heat capacity is the heat capacity per unit mass (J/g·K). Molar heat capacity is per mole (J/mol·K). Water has an exceptionally high specific heat capacity (4.184 J/g·K), which moderates Earth's climate. Heat capacity depends on the physical state and temperature of the substance.
