Question

To save on heating bills, do you think the roof of a building should be lined with

1. a thermal conductor

2. a thermal insulator

3. nothing

Answer 1

A thermal insulator because it would keep the heat in

Answer 2

2. a thermal insulator

Step-by-step explanation:

To save on heating bills, the roof of a building should be lined with a thermal insulator.

A thermal insulator will help prevent the house from loosing the heat trapped within the house.

• An insulator is a substance or device that does not allow for the conduction of heat and electricity.
• In this problem, an insulator does not allow for heat conduction.
• A conductor will allow heat pass through readily.
• So, to trap heat within the house, an insulator is best used.
