Heating capacity of water

WebThermodynamic properties of water: Boiling temperature (at 101.325 kPa): 99.974 °C = 211.953 °F Bulk modulus elasticity: 2.15 x 10 9 Pa or N/m 2 Critical temperature : 373.946 °C = 705.103 °F Critical pressure: 217.7 … WebThe specific heat capacity (SHC) of water is high (4.2 J g –1 K –1) and so it takes a lot of heat to produce a relatively small temperature rise in water. Again, the water conducts the heat away from the hot spot. The high SHC of water is due to the strong intermolecular hydrogen bonding – it takes a lot of energy to separate water molecules.
