Enthalpy of vaporization is the energy required to convert one mole of a liquid into vapor at a constant temperature and pressure, reflecting the strength of intermolecular forces in the liquid. It is a critical parameter in thermodynamics, influencing processes like boiling, evaporation, and condensation in various industrial and natural systems.

Boiling is the process where a liquid turns into vapor when its vapor pressure equals the atmospheric pressure, occurring at a specific temperature known as the boiling point. This phase transition involves energy absorption, which is used to break intermolecular bonds rather than increase temperature, resulting in a constant temperature until all the liquid has vaporized.

Evaporation is the process by which molecules transition from a liquid state to a gaseous state, occurring when molecules at the surface gain enough energy to overcome intermolecular forces. This process is crucial for the water cycle, influencing weather patterns and climate by contributing to cloud formation and precipitation.

evaporation

Condensation is the process by which water vapor in the air is transformed into liquid water, typically forming droplets on surfaces or in the atmosphere as clouds. This phase change is crucial in the water cycle, impacting weather patterns and climate by facilitating precipitation and heat exchange in the atmosphere.
