Pieces of camphor placed on water move about rapidly. This is because of - (1) diffusion (2) viscosity (3) surface tension (4) capillarity

Description : Pieces of camphor placed on water move about rapidly. This is because of - (1) diffusion (2) viscosity (3) surface tension (4) capillarity

Last Answer : (3) surface tension Explanation: The Camphor slowly dissolves in the water lowering the latter's surface tension in the immediate neighbourhood. When after sometime the whole surface settles for the reduced tension, the movement of the camphor too short.

Description : Pieces of camphor placed on water move about rapidly. This is because of - (1) diffusion (2) viscosity (3) surface tension (4) capillarity

Last Answer : (3) surface tension Explanation: The Camphor slowly dissolves in the water lowering the latter’s surface tension in the immediate neighborhood. The stronger pull exerted by the uncontaminated portion of water brings about a movement of the surface and the camphor particles are carried along with it.
