Energy Transfer by heating - Conduction and Convection (GCSE PHYSICS AQA HIGHER)

Heat is THERMAL energy and is transferred in 3 different ways:

CONDUCTION
CONVECTION
RADIATION 

CONDUCTION and CONVECTION involve PARTICLES.
RADIATION involves ELECTROMAGNETIC WAVES.

Conduction:
HEAT energy can move through a substance by CONDUCTION.
Metals are GOOD conductors, but non-metals and gases are BAD conductors.

Metals are made of metal IONS and FREE ELECTRONS; The…
