Question

As a liquid cools, what happens to the evaporation rate?
a. It increases.
b. It decreases.
c. It does not change

Answer 1

Evaporation is the rate at which liquid changes into gas. The higher the temperature the higher the increased rate of evaporation.

So if the liquid cools which means the temperature reduces, the rate of evaporation would decrease.

So evaporation rate decreases.  B.
