Question

what is evaporation? discuss three factors on which evaporation depends

Answer 1

Hello Mate!

The process of change from liquid state to vapour state at any temperature below the boling point is called Evaporation.

Three factors that effect rate of evaporation are :-

1. Surface Area - The area of object exposed to atmosphere. Therefore we spread cloths while dry them

2. Wind - Wind speed when increases then it hits the surface and take wate molecules long with it. Hence, cloths dry faster in windy day.

3. Temperature - As temperature increases, kinetic energy which helps to overcome intemolecular force and they change their state. That's why cloths dry faster in hot dry day.

4. Humidity - Atmosphere holds definite amount of water and when it increases then atmosphere refuses to take any more water molecule fro. wet cloth or object. So cloths don't dry much on humid day.

Hope it was enough and most imporatnt,
Hope it helped 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.
