SPECIFIC HEAT CAPACITY OF WATER

Specific heat is the energy required to raise the temperature of a unit mass of a substance by one degree. In thermodynamics, there are two kinds of specific heats: Cv (specific heat at constant volume) and Cp (specific heat at constant pressure). Cv is the energy required to raise the temperature of a unit mass of a substance by one degree as the volume is held constant. Cp is the energy required to do the same as the pressure is held constant. The Cv and Cp are identical for incompressible substances.

What is the unit for specific heat capacity?

Common units for specific heats are kJ/(kg · °C) or kJ/ (kg · K) and Btu/ (lbm · °F) .

What is the Specific Heat of Water?

The specific heat capacity (cp) of water is 4182 J/kg°C at 20 °C (room temperature).

The water heat capacity calculator can be used to find the specific heat capacity of water (cp of water) at different temperatures.
