Question

What is the role of the air spaces in insulating materials? Select all that apply.

Answer 1

They put gaps between the particles to slow down conduction

They make the material thicker so energy has to travel a further distance.

Answer 2

Answer:The correct answers are:

1. They trap heat in the spaces.  

2. They puts gaps between the particles to slow down conduction.

3.The make the material thicker so energy has to travel a further distance.

Explanation:

Insulating materials are those substance which opposes the flow of current through them and makes up bad conductor. There are air spaces present between these substances which :

• Traps the heat in the spaces so that movement of energy can be prevented.
• These spaces put gap between the particles of substance so that conduction of heat can be prevented.
• Makes the material thick so that energy has to travel longer distance so that energy get lost or distributed in an insulator.
