Statement 2 : Wooden doors and windows imbibe water in rainy season and thus their volume is increased.

• A. Both statements 1 and 2 are correct
• B. Statement 1 is correct but statement 2 is incorrect
• C. Statement 1 is incorrect but statement 2 is correct

Answer 1

Answer: (A)

Wooden doors and windows adsorb water in humid rainy season and increase in their volume so that they are hard to open or close. If a dry piece of wood is placed in water, it swells and increases its volume. During imbibition, the water molecules get tightly adsorbed and become immobilised.
