Q.
Which of the following does not affect the rate of evaporation ?
(1) Wind speed
(2) Surface area
(3) Temperature
(4) Insoluble heavy impurities
Dear Student,
The correct option would be (4) Insoluble heavy impurities.
Because rate of evaporation changes with the wind speed, it increases with the increase in the wind speed and decreases with the decreases in wind speed. Also, surface area affects the rate of evaporation as larger surface area promotes evaporation and smaller surface area decreases the rate of evaporation. Another factor i.e. temperature, also changes the rate of evaporation. With the increase in temperature, rate of evaporation increases and with the decrease in temperature, it decreases.
But rate of evaporation doesn't gets affected by insoluble impurities, because these are going to stay as it is but the liquid will evaporate.
Regards.
