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 the 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.

1. Marble tile is a better conductor of heat than wooden tile.
2. A conductor may be defined as that material that allows the transfer of heat smoothly through it.
3. A thermal conductor is a material that allows the energy in the form of heat, to be transferred within the material, without any movement of the material itself.
4. Most metals are good conductors of heat, Gold, Silver, Copper, Aluminium, Iron, etc are good heat conductors as well as electrical conductors.
5. Marble tiles feel cold because it conducts heat differently than other surfaces, such as wood or carpeting.
6. Heat disappears very quickly in marble.
7. Marble has a classical elegance, and along with it, it has another benefit: On a hot day, a room with marble floors or countertops will feel cooler.
8. Marble is a high-density, hard stone which makes it easier for heat to transfer from warmer objects, such as our feet.
9. Marble tile will allow heat to pass through itself easily, a good thermal conductor quality keeping it cool on a winter morning.

Thus, the correct option is option A.
