To study and demonstrate the amount of water that is imbibed by raisins.

It is the phenomena wherein water adsorption takes place by substances without solution formation. Example: When seeds are immersed in water, they swell due to  imbibition . This swelling up causes a temporary increase in the volume of the cell and does not require energy as materials are transported passively. Raisins increase in size due to imbibition of water. The quantity of water imbibed can be obtained by considering the difference in the mass between the dry raisins and the swollen raisins.

It is transported through imbibition, diffusion, and osmosis.

They are the substances that imbibe water. Example of imbibants – Starch. The adsorbent is the liquid that is imbibed.

It primarily occurs due to the presence of lyophilic and hydrophilic colloids. Through the sub-microscopic capillaries that are located on the body’s surface water is imbibed. The imbibition of water continues until a dynamic equilibrium is established which causes an increase in the imbibant’s volume resulting in imbibitional pressure which is of enormous magnitude.

Some factors that can affect the imbibition rate are:

Raisins that are used in the experiment should be ensured of being dry and clean and having their stalks intact.
