Question

Explain tha factors affecting the rate of evaporation

Answer 1

Hello Mate!

Factors effecting evaporation are :-

1. Temperature = When the temperature increases then particles gain kinetic energy and overcome intermolecular force of attraction to change into gas without boiling.

● This is why its asked to dry clothes in sunlight and not in shade.

2. Surface Area = When the surface area increases then the rate of evaporation increases.

● We spread clothes in front of sun to increase sirface area.

● We are able to drink hot tea easily from soccer than a tea cup.

3. Wind Speed = When wind comes with high speed then it collides with surface and take water molecules away.

● Clothes dry faster in windy day.

4. Humidity = Humidity is amount of water vapour present already in atmosphere. So, when there is humidity then water vapour released during evaporation will not be accepted by air and rate of evaporation decreases.

● Clothes dry very slow in humid day.

[ ■ Note = Surface Area : Its often said to eat food in a plate instead of bowl so that food gets cool quicker and hence we are able to eat food fast. ]
