Question

what is evaporation & discuss in detail the factor affecting evaporation

Answer 1

Boiling takes place only when the vapour pressure of the liquid equals the atmospheric pressure whereas evaporation occurs at all temperatures.

Many factors affect evaporation:

1.Temperature
2.Surface area of the liquid exposed to the atmosphere
3.Wind speed and
4.Humidity

Thank you

Answer 2

The change of liquid into its vapour form at any temperature point is called as evaporation. Evaporation is a surface phenomena.

» The conditions that increases the rate of evaporation are :-

→ Increase in Temperature :- The increase in temperature makes evaporation faster.

→ Increase in Surface area :- Increasing the surface area also makes evaporation faster.

→ Increase in wind speed :- Increasing the wind speed increases evaporation rate.

→ Decreasing humidity :- Decreasing humidity increases the rate of evaporation for water.
