Question

Swelling of wooden doors during rainy season is due tothe

• A. Endosmosis
• B. Deplasmolysis
• C. Capillarity
• D. Imbibition

Answer 1

The correct option is D

Imbibition

The correct option is D.

Explanation of the correct option:

1. Imbibition is a special type of diffusion process where water is absorbed by the solids causing an increase in volume.
2. The water is absorbed by the surface of the solids, thus causing swelling.

Explanation of the incorrect options:

Option A

1. Endosmosis- It takes place when a cell is placed in a hypertonic solution. The water moves out of the cell making the cell flaccid.

Option B

1. Deplasmolysis - occurs when water molecules move into the cell during endosmosis when the cell is placed in a hypotonic solution.

Option C

1. Capillarity- when a liquid rises up or down against gravity it is known as Capillarity.

Final Answer: Swelling of wooden doors during the rainy season is due to imbibition.
