(C) When a dry wooden piece is soaked in water,it shows significant swelling and an increase in volume. This phenomenon is known as imbibition. Imbibition is a special type of diffusion where water is absorbed by solids (colloids),causing them to increase in volume. Wood is primarily composed of cellulose and proteins,both of which are hydrophilic substances that act as imbibants. Therefore,the swelling of wood in water is due to the imbibition of water by both cellulose and proteins.
