Answer 1

Answer:

1. C. Why a handle of a metal spoon also gets hot when  placed on a steamy soup.

2. D. It determines the hotness or coldness of an object.

3. D. Energy transferred due to temperature differences.

4. C. The object is a thermal insulator.  

Explanation:

Convection is the transfer of heat energy through the movement of a liquid or gas from one place to another. If we place a metal object at a distance from the hot body so the fumes that comes out increase the temperature of the metal that is present on the hot body. Temperature determines the hotness or coldness of an object not the heat. The heat energy transferred from one body to another due to difference in temperature of both objects. Insulator are those materials which no ability to transfer heat energy from one place to another.
