Answer 2

Answer:

1.factor responsible for the change in rate of evaporation are:

Temperature: As the temp of the earth increases,the rate of evaporation also increases.

Humidity: Increase in humidity leads to decrease in rate of evaporation.

Surface area:When area increases,the rate of change of evaporation decreases and when the area decreases rate of change of evaporation increase s.

2... Since humidity is the amount of moisture or water vapour present in the air.So, if the humidity is high it means that the outside medium already has a lot of water vapour.Therefore,it will not take more water vapour on evaporation of water.Thats why,the rate of evaporation decreases with increase in humidity in an aqueous solution.
