Class 11 Chemistry Gases & Solutions States of Matter



Why does a small piece of camphor dance about on the water surface?
Solution: The camphor slowly dissolves in the water lowering the water's surface tension in the immediate neighbourhood. The strange pull exerted by the uncontaminated portion of water brings about a movement of the surface and the camphor particles are carried along with it. When after sometime the whole surface settles for the reduced tension, the movement of the camphor too stops.
