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.
L is the specific latent heat of vaporization and is the heat required to convert a unit mass of liquid into vapour at the same temperature as the boiling point. L and the boiling temperature, both depend on the pressure. Heat transfer occurs between bodies that are in contact with each other.
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.
The long stretches of constant temperature values at \(0^oC\) and \(100^oC\) reflect the large latent heat of melting and vaporization, respectively. Water can evaporate at temperatures below the boiling point.
It is an important thermodynamic property for thermal desalination and water treatment processes, especially when water is separated by vaporization. This chapter introduced the thermodynamic approaches, correlation, and data used to estimate latent heat of vaporization at different salinity and temperature values.
latent heat of vaporization: the energy required to transition one unit of a substance from liquid to vapor; equivalently, the energy liberated when one unit of a substance transitions from vapor to liquid.
