The latent heat calculator helps you compute the energy released or absorbed during a phase transition like melting or vaporizing. In the text below, we explain what is specific latent heat and present a simple latent heat calculation.
Thermal properties of water at different temperatures like density, freezing temperature, boiling temperature, latent heat of melting, latent heat of evaporation, critical temperature and more. Thermodynamic properties of water: Boiling temperature (at 101.325 kPa): 99.974 °C = 211.953 °F.
In thermodynamics, the enthalpy of vaporization (symbol ∆Hvap), also known as the (latent) heat of vaporization or heat of evaporation, is the amount of energy (enthalpy) that must be added to a liquid substance to transform a quantity of that substance into a gas.

How to heat water What is the specific heat capacity? How do you calculate the energy needed to heat water? Changing the temperature of ice — an example FAQs.
Take, for example, the fact that, at body temperature, perspiration from the skin requires a heat input of 2428 kJ/kg, which is about 10 percent higher than the latent heat of vaporization at \(100^oC\). This heat comes from the skin, and thus provides an effective cooling mechanism in hot weather.
Even more energy is required to vaporize water; it would take 2256 kJ to change 1 kg of liquid water at the normal boiling point (100ºC at atmospheric pressure) to steam (water vapor). This example shows that the energy for a phase change is enormous compared to energy associated with temperature changes without a phase change.
