Heat - Insulation - Conduction.
We have seen that non-metals are
good insulators.
Examples of non-metals used as
insulators include
wood, glass and plastics (polymers).
You can find out more about polymers
on the GCSE Chemistry site
at Polymers.
Gases
are particularly good insulators if
you can stop them moving.
This prevents them transferring
heat by convection.
A layer of air is trapped by our clothing to keep us warm.
The trapped air
slows down the rate of
heat loss
by conduction
from our bodies.
The fur of animals also
traps a layer of
air to keep them warm.
When the animal is cold, its fur
stands up more to trap more air.
The same idea can be used to insulate
buildings.
