Question

Mehak notices that the ladle she is using to make soup is made of two materials (wood and steel). She observes that the handle of the ladle is cool, but the other end is hot. How can the two materials be classified based on conduction of heat?
1 point
Wood and steel are good conductors of heat
Steel and wood are bad conductors of heat
Wood is a good conductor of heat, but steel is not
Steel is a good conductor of heat, but wood is not​

Answer 1

Answer:

4

Explanation:

Steel is a good conductor while wood is not!

Answer 2

The correct answer is- Steel is a good conductor of heat, but wood is not.

• Conductors are the materials that allow the heat to travel through them due to the presence of free electrons.
• All the metals are good conductors of heat e.g. silver.
• As silver is a good conductor of heat, it becomes hot when it comes in contact with heated substance.
• Wood is not a metal and hence, it is a poor conductor of heat. It is used to make handles of several cooking appliances as it remains cool even when it comes in contact with heated objects.
