apa kepaleku sdg pikir

1) Conduction : heat is conduct by the transfer of energy of motion between adjacent motions,which from greater energy levels to the lower energy levels.It can also transfer in free electrons in metallic solids.

2)convection: heat is transfer implies by bulk transport and mixing of macroscopic elements.It is normally involve energy exchange between a solid surface and a fluid.The fluid is forced to flow past a solid surface by pump.

3) radiation : Heat transfer that not required physical medium at all. It is not same as convection and conduction that has medium for propogate. It is transfer of energy through space by means of electromagnetic waves.

mood: testo testo.haishh!
