Question

Explain any two factors affecting the rate of evaporation

Answer 1

rate of evaporation is affected by

1. surface area as the surface area increases the rate of evaporation increases .

2. humidity increase in humidity decreases the rate of evaporation as there are already more amount of water vapour in air hence decreasing the rate .

Answer 2

Answer:

• Temperature :

As the temperature increases, the rate of evaporation also increases. Temperature and rate of evaporation are proportional to each other.

• Surface area :

As the surface area increases, the rate of evaporation increases. The surface area and rate of evaporation are proportional to each other.

• Humidity :

The rate of evaporation decreases with an increase in humidity. Humidity and the rate of evaporation are inversely proportional to each other.

• Wind speed :

Increase in wind speed results in increased evaporation. Wind speed and rate of evaporation are proportional to each other.
