Grade 7 Conduction Notes


Conduction

·        The transfer of heat through a solid or between a solid and another solid, a liquid, or a gas that is in contact with it
·        Conduction can also occur from liquid to solid and gas to solid
·        Conduction always occurs from a warmer region to a cooler region
·        Conduction occurs when warmer particles bump into cooler particles making them vibrate faster
·        Metals are better heat conductors than non-metals because they have free electrons
