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

They trap heat in the spaces.
Allow electrons to move around more freely
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.
