• The materials which allow heat to páss through them are called good conductors of heat.

• The materials which does not allow heat to páss through them are called bad conductors of heat.

• All metals are good conductors of heat.

• All materials do not have equal conductivity.

• Iron, copper and aluminum are preferred to make the cooking vessels due to their high conductivity of heat.
