Heat capacity of water in btu
WebThe value of the specific heat of water vapor can be expressed in different forms as follows. Specific Heat Of Steam In J/Kg-K. In SI units, the isobaric, or constant pressure, specific heat of steam is equal to 1,864 J/kg-K, while its isochoric, or constant volume, specific heat is equal to 1,402 J/kg-K at 300 K. Specific Heat Of Steam In Btu ... WebHeat capacity. The specific heat capacity of water is 4,200 Joules per kilogram per degree Celsius (J/kg°C). This means that it takes 4,200 J to raise the temperature of 1 kg of water by 1°C.
