Explanation:Ans 1. Evaporation and Condensation are occurring in the figure Evaporation:Evaporation is a type of vaporization that occurs on the surface of a liquid as it changes into the gas phase.
Condensation:Condensation is the process by which water vapor in the air is changed into liquid water. In other words, the water in the air, a gas known as water vapor, from your hot shower cooled when it met the surface of the cold mirror.
Ans 2. Differences between Evaporation and condensation
Evaporation and Condensation 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.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.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..
Evaporation can occur in all surfaces, at all times and at all places.
Evaporation is frequent when the air is dry, hot and windy.
Condensation takes place on salt, hygroscopic nuclei-pollen grains,carbon particles etc.when air temperature is decreased beyond the level of saturation.
Evaporation usually takes place in low altitudes.
Condensation happens mainly at higher altitudes.When evaporation takes place energy is consumed.

Answer:
1) Evaporation and condensation.
2) a. Evaporation:
- process where water change into vapour.
- It occurs before a liquid reaches in boiling point.
b. Condensation:
- process where water vapour is converted into tiny droplets of water.
- It is a phase change regardless to the temparature.
