Raisins absorb water by___________.
Imbibition
Imbibition is a form of diffusion where water is absorbed by solids or colloidal substances and it does not form a solution; instead, the water imbibed gets associated with the highly hydrophilic solid substances. Swelling of raisins when immersed in water is an example of imbibition. Imbibition occurs through passive transport and does not require energy.
