Question

Imbibition involves

• A. Diffusion of water
• B. Movement of water into imbibant through capillarity
• C. Movement of water into imbibant through diffusion as well as capillary action
• D. Adsorption of water

Answer 1

The correct option is C Movement of water into imbibant through diffusion as well as capillary action

The process of adsorption of water by solid particles of a substance without forming a solution is called imbibition. The soild substance which absorbs water is known as imbibant. Water molecules are at constant random motion because of its less viscosity so it has greater kinetic energy. Due to its kinetic energy, water is adsorbed by the surface from higher concentration to lower concentration by the process of diffusion or capillary action. The kinetic energy is released as heat.

So, the correct answer is option C.
