Answer 1

Answer:

The other factors that affect evaporation are surface area, temperature and air ... You can do a few fairly simple experiments to demonstrate the effect that the ... Test this by putting water into two different containers.

Explanation:

On a hot dry day, the amount of water vapour present in the air is less. Thus, water present inside the desert cooler evaporates more, thereby cooling.
