1.

List the factors on which evaporation depends?

Answer»

Solution :1. Surface area exposed to atmosphere. Since evaporation is a surface phenomenon, therefore it increaseswith an INCREASEIN surface area.
2. HUMIDITY :- The air around us cannot hold more than definite amountof water vapour at a giventemperature. If the amount of water in air already high, the rate of evaporation DECREASES. So, evaporation decreases with INCREASE in humidity.
3. Wind Speed : With the increasein wind speed, the particlesof water vapour move away with the wind, decreasing the amount of water vapour in the surrounding. This results in a factor rate of evaporation, So, evaporation with the increase in wind speed.
4. An increase, more number of particles get enough kinetic energyto go into the vapour state.
