IPC Notes: Heat Transfer
Conduction – the transfer of heat by direct contact of particles
Thermal conductors – materials that conduct heat easily
ex) metals
Comparison of some thermal conductors:
Thermal insulators – materials that conduct heat poorly
ex) plastic, wood, rubber & glass
Convection – transfer of heat by the actual motion of a fluid in the form of currents
warm fluids rise & cooler fluids sink
Radiation – transfer of heat by electromagnetic waves
