Specific latent heat is the amount of energy required to change the state of 1 kilogram (kg) of a material without changing its temperature. Energy input but no increase in temperature energy required to overcome attractive forces between molecules. As it is heated further, the energy from the heat source goes into breaking. To increase the temperature of an object it is necessary to increase the thermal energy of the molecules of the substance. The (latent) heat of vaporization (∆hvap) also known as the enthalpy of vaporization or evaporation, is the amount of energy (enthalpy) that must be added to a liquid substance, to the calculator below can be used to calculate the liquid water heat of vaporization at vapor pressure at given temperatures. Starting a point a, the substance is in its solid phase, heating it brings the temperature up to its melting point but the material is still a solid at point b.
Specific latent heat coefficient of the material j/kg.
Starting a point a, the substance is in its solid phase, heating it brings the temperature up to its melting point but the material is still a solid at point b. The specific latent heat of vaporisation of a substance is usually larger than the specific latent heat of fusion. Endothermic phase changes absorb heat from the environment.
