Question

Explain the evaporation of liquid on the basis of kinetic theory.

Answer 1

Evaporation is a process of change of a liquid into gas below its boiling point.

• Example water changes into water vapors without heating at 100 ^oC.

Explanation of Evaporation of liquid on the basis of kinetic theory:

• According to kinetic theory, liquid molecules are in a state of continual random motion.
• When the temperature is raised, the liquid converts to water vapor during the evaporation process.
• This kinetic energy is sufficient to break the intermolecular attraction between molecules, allowing the molecules to escape the container and travel apart. In the form of a gaseous state.
• Evaporation occurs as a result of this kinetic energy theory.
• When the temperature is raised, the liquid converts to water vapor during the evaporation process.
• Thus in this way evaporation of liquid takes place.
