Select correct statement w.r.t. imbibition
(1) Starch is the best imbibant
(2) It involves capillary action, not diffusion
(3) Volume of the imbibant increases
(4) Cellulose is the best imbibant
Volume of the imbibant increases with the imbibition of water. This results in imbibitional pressure. Hence, option (3) is correct.
