Solution
The rate of evaporation depends on the surface area of the container. The more the surface area, more is the more evaporation. It also depends on the speed of the wind. If the speed of the wind is more, more number of particles will evaporate from the surface. Hence, in figure (C) in which both these factors, surface area, and moving fan are there, the rate of evaporation will be maximum.

The scientists now say that there are actually five states of matter A, B, C, D and E. The state A has a fixed volume but no fixed shape. The state B can be compressed very easily by applying pressure and state C has a fixed shape as well as a fixed volume. The state D is a mixture of free electrons and ions whereas state E is named after an Indian scientist and a famous physicist.
