Question

1(a)what is a meant by evaporation what are the factor on which the rate of evaporation depend upon(b) how does evaporation causes cooling

Answer 1

evaporation is the simple process which occurs when water changes into it's gaseous form due to high pressure and temperature

Explanation:

a) the factors affecting the rate of evaporation are

increase in temperature

increase in area

increase in wind speed

decrease in humidity

b) as a result of loss of heat energy from the surrounding the particles of the liquid gain energy from the surrounding to overcome the force of attraction during evaporation which causes cooling effect
