Radiation

HEAT TRANSFER.

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.
