Answer:
By definition, evaporation is a process where water changes into vapour. Condensation is the opposite process where water vapour is converted to tiny droplets of water. Evaporation occurs before a liquid reaches its boiling point. Condensation is a phase change regardless of the temperature.

# Evaporation
- By definition, evaporation is a process where water changes into vapour.
- Evaporation occurs before a liquid reaches its boiling point.
- In terms of molecular movement, when a liquid is heated or when pressure is decreased the forces of attraction between molecules is low. The liquid then evaporates to a gas.
- Evaporation can occur in all surfaces, at all times and at all places. Evaporation is frequent when the air is dry, hot and windy.
- Evaporation usually takes place in low altitudes.
- When evaporation takes place energy is consumed.
# Condensation
- Condensation is the opposite process where water vapour is converted to tiny droplets of water.
- Condensation is a phase change regardless of the temperature.
- When a gas is cooled or when the pressure is increased the forces of attraction between molecules become strong. The gas then condenses to either a liquid or even a solid.
- Condensation takes place on salt, hygroscopic nuclei-pollen grains, carbon particles etc.when air temperature is decreased beyond the level of saturation.
- Condensation happens mainly at higher altitudes.
