What is diffusion?
(a) What is diffusion? (b) State two factors which affect the rate of diffusion. This is a process whereby the molecules of a substance migrate from a region of higher concentration to a region of lower concentration due to their random thermal motions. The factors that affect the rate of diffusion include: Concentration of the […]
Explain the rise of water…
Explain the rise of water in a glass capillary tube using the kinetic theory. Solution Glass and water are composed of molecules. The force of attraction between water molecules and glass molecules are stronger than that among water molecules. Therefore, there is rise in a glass capillary tube. Capillary action is one of the effects […]
