 Evaporation occurs at the surface of a liquid because the particles at the surface:

  • a)
    have sufficient energy to break through the forces of attraction between them

  • b)
    are very light as compared to the particles beneath

  • c)
    are pulled by the particles of air with more force

  • d)
    are pushed up by the particles beneath

Correct answer is option 'A'. Can you explain this answer?

Surface Evaporation Explanation:

Evaporation occurs at the surface of a liquid because the particles at the surface:

Have Sufficient Energy:
- The particles at the surface of a liquid have sufficient energy to break through the forces of attraction between them.
- This energy allows them to overcome the intermolecular forces holding them together in the liquid phase.

Energy Required:
- In order to evaporate, particles at the surface must have enough kinetic energy to escape the liquid phase and enter the gas phase.
- This energy requirement is met by the particles at the surface that have absorbed enough energy from the surroundings.

Increased Kinetic Energy:
- Due to their position at the surface, these particles are exposed to the surrounding environment, which can provide them with additional kinetic energy.
- This increased kinetic energy allows them to break free from the liquid and evaporate into the gas phase.

Overall Process:
- In summary, evaporation occurs at the surface of a liquid because the particles at the surface possess the necessary energy to overcome the attractive forces between them and transition into the gas phase.
