Question

3. Explain how the following factors affect the rate of evaporation of a liquid-
a) Temperature of a liquid
b) Area of the exposed surface
c) Moisture in the surrounding air.

Answer 1

Answer--

a) Temperature of the liquid- Temperature is directly proportional to evaporation if the temperature of the liquid is higher then the evaporation process will also be higher and if the temperature of the liquid is lower then the evaporation process is is also time taking.

It is because I hot liquid boils fastly and evaporated fastly so the temperature of liquid affect the rate of evaporation.

b) Area of the exposed surface-

Evaporation is a surface phenomenon.The larger the area of exposed surface the rate of evaporation is also high the smaller the area of surface exposed the rate of evaporation is also low .Area of exposed surface affect the rate of evaporation of a liquid . A liquid in a big surface evaporates fastly as compared to in small surface. Like afford thing is getting cooler in big surface fastly as compared to a small surface.

c) Moisture in surrounding air-

If the moisture is low in the air then the evaporation rate will be faster and if the moisture is high in air then the evaporation rate will be low.
