Applications of conductors



Heat is transferred in matter through the following methods: conduction, convection and radiation. Conduction This is the transfer of heat in solids. The rate of conduction depends on Amount of temperature – the higher the temperature the higher the rate of transfer. Cross-sectional area – the larger the cross-sectional area the higher the transfer. Length of material – the shorter the material the higher the rate of transfer. Type of material – different materials transfer heat at different rates.   Good and bad conductors Conductivity is the ability of a material to conduct heat. Good conductors of heat are those materials which are able to transfer heat easily and steadily. Bad conductors are those which do not conduct heat. Experiment: Comparing thermal conductivity of metals Procedure Obtain four identical rods of copper, iron, aluminium and brass. At one end of each rod attach a matchstick using paraffin wax and let… Read More »HEAT TRANSFER
