Question
The evaporation of water increases under the following conditions :
Options
increase in temperature, decrease in surface area
increase in surface area, decrease in temperature
increase in surface area, rise in temperature
increase in temperature, increase in surface area, addition of common salt
Solution
increase in surface area, rise in temperature
When surface area increases and temperature rises, evaporation of water increases because the area which is exposed to the outer atmosphere is more and increasing the temperature leads to increase in the kinetic energy, due to which rate of evaporation increases.
