Question 1

A marble tile would feel cold as compared to a wooden tile on a winter morning, because the marble tile

(a) Is a better conductor of heat than the wooden tile.

(b) Is polished while wooden tile is not polished.

(c) Reflects more heat than wooden tile.

(d) Is a poor conductor of heat than the wooden tile.

Answer 1

Marble tile is a better conductor of heat. When you step on the marble heat transfer occurs from your palm to marble. This is the reason you feel cold. Whereas wood is a poor conductor of heat, less heat transfer occurs between you and wood, that is why you do not feel much cold. So, the answer is (a).
