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

Conduction, Convection or Radiation Identify the following as either conduction, convection or radiation: The sun warms your skin Radiation
