Question

What is the role of the air spaces in insulating materials? Select all that apply.
They trap heat in the spaces.
They puts gaps between the particles to slow down conduction.
They dissipate energy faster.
The make the material thicker so energy has to travel a further distance.
Allow electrons to move around more freely

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.
