Question

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

The correct option is A is a better conductor of heat than the wooden tile.

Marble tile is better conductor of heat, hence when you step on the marble greater heat transfer occurs from your palm to marble. This is the reason you feel cold. Whereas wood is bad conductor of heat, hence less heat transfer occurs between you and wood, that is why you do not feel much cold.
