  1. Equal amount of water was filled in all the containers and kept under the Sun. The rate of evaporation was faster in the container “C”. Why?

(A) Smaller is the surface area of liquid exposed to the heat, faster is the rate of evaporation

(B) Container “C” is flat, evaporation occurs faster in the flat surface as compared to the curved surface

(C) Container “C” is broad, maximum surface area of liquid gets exposed to heat which in turn allows maximum evaporation
