उत्तर
A marble tile would feel cold as compared to a wooden tile on a winter morning because the marble tile is a better conductor of heat than wooden tile.
Explanation:
Marble is a better conductor of heat compared to wood. When you touch a marble tile on a cold winter morning, it quickly conducts heat away from your body, making it feel colder. In contrast, wood is a poor conductor of heat, so it doesn’t draw heat away from your body as quickly, making it feel warmer in comparison.
