Question

Two students A and B were given 10 ml of water in a bowl and plate respectively. They were told to observe the rate of evaporation. Name the students whose water evaporate faster and explain its reason.

Answer 1

water in plate evaporates faster

rate of evaporation increases with increase in surface area of the vessel

Answer 2

Water in the plate evaporates faster because the rate of evaporation is directly proportional to the surface area. Since plate has more surface area than bowl the water in plate evaporates faster.
