Question

List the factors that determine the rate of evaporation and explain the dependency on each.

Answer 1

Factors that affect the rate of evaporation are:

1. Surface area

1.1 The rate of evaporation directly depends on the surface area of the substance.

1.2 The higher the surface area the greater the rate of evaporation.

2. Temperature:

2.1 The rate of evaporation is directly dependent on the temperature rise.

2.2 The higher the increase in temperature, the more the rate of evaporation

3. Wind:

3.1 The wind also contributes as a factor to the rate of evaporation.

3.2 The more the speed of blowing wind, the higher the rate of evaporation.

Hence, the rate of evaporation depends on the Surface area, Temperature, and Wind.
