GENERAL HISTOLOGY

Detailed explanation-1: -energy known as the latent heat of vaporization is required to break the hydrogen bonds. At 100 °C, 540 calories per gram of water are needed to convert one gram of liquid water to one gram of water vapour under normal pressure.

Detailed explanation-2: -Boiling and Evaporation: Evaporation is the change of a substance from a liquid to a gas. Boiling is the change of a liquid to a vapor, or gas, throughout the liquid.

Detailed explanation-3: -The enthalpy of vaporization (symbol ∆Hvap), also known as the (latent) heat of vaporization or heat of evaporation, is the amount of energy (enthalpy) that must be added to a liquid substance to transform a quantity of that substance into a gas.

Detailed explanation-4: -Heat of Vaporization Explained As the molecules gain more kinetic energy, they become more likely to separate from the liquid and become a gas. The required increase in internal energy can be described as the energy needed to break the intermolecular interactions in the liquid.
