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
