Science – Heat Transfer
Posted June 22, 2016on:
Conduction – transfer of thermal energy between regions of matter due to a temperature difference through the matter itself, without displacing the molecules. E.g. the spoon becomes hot when you put it into a hot soup.
Convection – transfer of thermal energy between regions of matter due to the density difference through the movement of molecules. E.g. hot air moves up.
Radiation – transfer of thermal energy through space. E.g. the heat from the Sun travels to the Earth.
