What is the heat of vaporization of water?

On the other hand, the molecules in liquid water are held together by relatively strong hydrogen bonds, and its enthalpy of vaporization, 40.65 kJ/mol, is more than five times the energy required to heat the same quantity of water from 0 °C to 100 °C (cp = 75.3 J K1 mol1).

What is the definition of latent heat of vaporization?

Latent heat is energy released or absorbed, by a body or a thermodynamic system, during a constant-temperature process. Two common forms of latent heat are latent heat of fusion (melting) and latent heat of vaporization (boiling). In both cases the change is endothermic, meaning that the system absorbs energy.

What is meant by the latent heat of vaporization?

Whether, a substance is converting from solid to liquid or liquid to gas, we use this term latent heat. So lets come to latent heat of vaporization. So, the amount of heat required to convert a substance from liquid to vapor at a given saturation temperature and pressure is called latent heat of vaporization.
