The average distance between molecules in a liquid is much smaller than that in a gas. During vaporization, the average distance between molecules increases and the volume expands sharply; work must be done to overcome the intermolecular forces as well as resist atmospheric pressure. Therefore, vaporization absorbs heat. The heat absorbed per unit mass of liquid when it transforms into vapor at the same temperature is called the latent heat of vaporization, or simply vaporization heat.
Latent heat of vaporization refers to the amount of heat absorbed per unit mass of a liquid substance during the vaporization process, with constant temperature.

The latent heat of vaporization is the amount of heat absorbed per unit mass of a liquid substance during the vaporization process, with temperature remaining constant. Vaporization occurs in two ways: evaporation and boiling. Both absorb heat, and evaporation occurs only at the liquid surface. Boiling occurs simultaneously inside and on the surface of a liquid. Latent heat of vaporization: The average distance between liquid molecules of the same substance is much smaller than that in the gas state. During vaporization, the average distance between molecules increases and the volume expands sharply; work must be done to overcome the intermolecular forces as well as resist atmospheric pressure. Therefore, vaporization absorbs heat. The heat absorbed per unit mass of liquid when it transforms into vapor at the same temperature is called the latent heat of vaporization, or simply vaporization heat. It decreases as the temperature rises, because at higher temperatures the liquid molecules possess more energy, reducing the difference between the liquid and gas phases. At the critical temperature, a substance is in a critical state; the difference between the gas and liquid phases disappears, and the heat of vaporization is zero. The process by which a substance changes from a liquid state to a gaseous state is called vaporization.
That is, the heat absorbed per unit mass of a liquid substance during vaporization, when the temperature remains constant.
