Question

Wooden doors and windows swell up in the rainy season by
(A) A special type of diffusion called imbibition
(B) Evaporation of stored water wood
(C) Conduction of water from walls
(D) Transpiration

Answer 1

Hint: In the wet season when there is high humidity, and an abundance of moisture in the air, the wooden doorways get tight due to the fact they absorb moisture. It is a transient process, as the door shrinks as quickly as the humidity decreases.

Complete answer:
- The swelling of wooden doorways is brought about via the manner of imbibition. Imbibition is the absorption of water by solid particles of a substance barring forming a solution. The two fundamental things for imbibition are absorbent (wooden frame) and liquid imbibed (water). Some examples are swelling of wooden furniture, doors, windows, and frames of doors, etc.

-The absorption of water with the aid of seeds and dry timber is additionally an instance of imbibition. Seedlings emerge from the soil due to the strain by way of imbibition. The Water surface possible movement takes place alongside a concentration gradient and some dry materials soak up water. A gradient between the absorbent and the liquid is fundamental for imbibition.

-For a substance to imbibe a liquid, there ought to first be some shape of appeal between them. Another example of imbibition in nature is the absorption of water with the aid of hydrophilic colloids. Matrix viable contributes significantly to water in such substances. Imbibition can also control circadian rhythms in Arabidopsis thaliana and (probably) other plants.

- Due to the excessive imbibition capacities in proteins, proteinaceous pea seeds swell greater than starchy wheat seeds. Starch has less and cellulose has the least imbibing capacity.

- Imbibition of water increases imbibing volume, which results in imbibitional pressure (IP). The magnitude of such strain can be tested by using the splitting of rocks via inserting dry timber stalks in their crevices and soaking them in water, a technique used by using early Egyptians to cleave stone blocks. Skin grafts acquire oxygenation and nutrition via imbibition, keeping mobile viability until the tactics of inosculation and revascularization have re-established a new blood furnish inside these tissues.

Thus the correct answer is option ‘A’.

Note: In short, it can be stated that imbibition occurs when a wetting fluid displaces a non-wetting fluid. The imbibing has a high terrible water practicable referred to as the matrix potential. And making it bigger in temperature is also integral for the imbibition to occur.
