Question

Identify and explain the factor responsible for changed rate of
evaporation in the following situations:
(a) While putting clothes for drying, we spread them out.
(b) Water coolers are not effective on a rainy day.

Answer 1

Answer:

A) while putting clothes for drying we spread them out as it increases the surface area which in turn helps to increase the rate of evaporation. ... The heat evaporates along with water to provide cool air. But, on a rainy day, there is high humidity which reduces the rate of evaporation, thus reducing the cooling effect.
