METHODS OF HEAT TRANSFER

CONDUCTION – CONVECTION - RADIATION

TRANSMISSION OF HEAT

•MOVEMENT OF HEAT FROM COLDER TO HOTTER ITEM

CONDUCTION•OCCURS WHEN TWO OBJECTS TOUCH•CONDUCTORS- MATERIALS THAT ARE READY TO CONDUCT HEAT•INSULATORS- MATERIALS THAT SLOW DOWN CONDUCTION OF HEAT

CONVECTION

•OCCURS IN ALL UNEVENLY HEATED LIQUIDS AND GASSES•OCCURS WHEN HEATED SUBSTANCE ITSELF MOVES

RADIATION

•ONLY TYPE OF HEAT TRANSFER THAT CAN OCCUR IN EMPTY SPACE
