What Does Enthalpy of Vaporization Mean?
Enthalpy of vaporization is an important property of any liquid, which states that when heat or enthalpy is given to any liquid substance at a certain pressure and temperature, the liquid changes into a gaseous form. Thus, a transformation from one state to other state occurs.
Enthalpy of vaporization is also known as latent heat of vaporization, or heat of vaporization.
Corrosionpedia Explains Enthalpy of Vaporization
Enthalpy of vaporization refers to the physical
destruction of an object that is exposed to intense heat. Enthalpy of
vaporization is a function of the pressure at which the transformation from one state
to other occurs. Heat of vaporization is mainly of two types: evaporation and boiling.
Evaporation is a transition
phase of a substance in which a liquid is converted into a vapor at
a temperature lower than the boiling point at a given pressure.
Evaporation only occurs when the equilibrium vapor pressure is greater than the
partial pressure of the vapor. Boiling is also a phase transition from a liquid
to a gas, but it is the formation of bubbles below the surface of the liquid.
Boiling occurs when the environmental pressure is less than or equal to the equilibrium vapor pressure of the substance.
