Webb23 aug. 2024 · The Clausius-Clapeyron equation relates the latent heat (heat of transformation) of vaporization or condensation to the rate of change of vapour … WebbThis equation can be rearranged with the help of a formula triangle: For context, the values of latent heat for water are: Specific latent heat of fusion = 330 kJ/kg. Specific latent heat of vaporisation = 2.26 MJ/kg. Therefore, evaporating 1 kg of water requires roughly seven times more energy than melting the same amount of ice to form water.
WebbSpecific heat is closely related to the concept of heat capacity. Heat capacity is the amount of heat necessary to change the temperature of a substance by 1.00 °C . In equation form, heat capacity C is C = m c, where m is mass and c is specific heat. Note that heat capacity is the same as specific heat, but without any dependence on mass.
