$\bf\underline{\underline{Qᴜᴇsᴛɪᴏɴ}}$

(a) Enumerate the change that takes place in liquid during evaporation.

(b) How is the rate of evaporation affected by change in the following? Justify your answer.
i. Temperature
ii.wind speed
iii. humidity.

Answer 1

Answer:

(a) Enumerate the change that takes place in liquid during evaporation.

during evaporation , a small fraction of particles at the surface having higher KE is able to break away from the force of attraction of other particles and gets converted into vapour.

(b) How is the rate of evaporation affected by change in the following? Justify your answer.

i. Temperature

increases with the temperature due to increases in KE of the particles

ii.wind speed

increases with wind speed as the particles of water vapour move away with the wind. decreasing the amount of water vapour in the surrounding.

iii. humidity.

decrease with humidity as the amount of water vapour in air is already high.
