Question

Explain how the rate of evaporation of liquid is affected with
a)increase in temperature of the liquid.
b)decrese in exposed surface area.
c)increase in the moisture in the surrounding air.
d)increase in wind speed.

Answer 1

a) Increase in temperature of the liquid

As temperature increases rate of evaporation will increase.

b) Decrees in exposed surface area

As surface area decreases rate of evaporation will decrease.

c) Increase in the moisture in the surrounding air

As moisture in the surrounding air increases, humidity increases and thus rate of evaporation will decrease.

d) Increase in wind speed

As wind speed increases rate of evaporation will increase.

Answer 2

Explanation:

• lncrease in temperature:- Rate of evaporation increases. when the temperature of a liquid is increased by heating it more particles of liquid get get enough kinetic energy to go into the vapour state.

• decrease e in exposed surface area:- Rate of evaporation decreases. Larger surface area gives the particles of liquid a greater chance of escaping from the liquid; if the surface area is lowered, rate of evaporation decreases too.

• Increase in the moisture in the atmosphere:- Rate of evaporation decreases. When the humidity is already high in the atmosphere, the rate of evaporation slows down because of the amount of water vapour present there already and leaving less or no space for the new vapours.

• Increase in wind speed:- Rate of evaporation increases. When the speed of wind increases the particles of water vapour move away with the wind decreasing the amount of water vapour already present in the atmosphere.

Hope that helps.
