Question

Dry wooden stakes driven in cracks of a rock and soaked will develop pressure that will split the rock. The phenomenon is

• A. Osmotic pressure
• B. Imbibition
• C. Turgor pressure
• D. Deplasmolysis

Answer 1

The correct option is B Imbibition

(A) Osmotic pressure is the pressure applied to the pure solvent to prevent it from passing a solution.

(B) Imbibition is the flow of water from the outer environment to solids like wooden things. Eg. Water flows into wooden doors and rocks.

Due to imbibition only dry wooden stakes driven in cracks of rock and soaked will develop pressure that will split the rock.

(C) Turgor pressure is the pressure applied by the osmotic flow of water on the walls of the cell.

(D) Deplasmolysis is the entrance of water into a plasmolysed cell.

So, the correct answer is 'Imbibition'.
