In thermodynamics, the enthalpy of vaporization (symbol ∆H vap), also known as the (latent) heat of vaporization or heat of evaporation, is the amount of energy that must be added to a liquid substance to transform a quantity of that substance into a gas.
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.
5 kwi 2016 · Latent heat refers to the heat required to overcome molecular bonds. Latent heat of vapourisation of water at 1 bar, $100^\circ C$ is $2257 \frac{kJ}{kg}$. Which means, that much heat is required to break inter-molecular forces and turn into gasoeus phase.
The heat Q required to change the phase of a sample of mass m is given by \(\mathrm{Q=mL_f}\) (melting or freezing) and \(\mathrm{Q=mL_v}\) (evaporating or condensing), where \(\mathrm{L_f}\) and \(\mathrm{L_v}\) are the latent heat of fusion and the latent heat of vaporization, respectively.
Abstract The latent heat of vaporization/condensation of saline water represents the energy needed for phase change from liquid to vapor or reverse. It is an important thermodynamic property for thermal desalination and water treatment processes, especially when water is separated by vaporization.
