HEAT

HEAT TRANSFER

• thermal engineering that concerns the generation, use, conversion, and exchange of thermal energy and heat between physical systems.

CONVECTION

• Convection is the concerted, collective movement of groups or aggregates of molecules within fluids

CONDUCTION

• In conduction heat spreads through a substance when faster atoms and molecules collide with neighboring slower ones, transferring some of their kinetic energy to them.

RADIATION

• radiation is a process in which energetic particles or energetic waves travel through a vacuum, or through matter-containing media that are not required ...

DOES HEAT TRANSFER NEED MATTER

• Yes except radiation because radiation uses EM waves.

DOES HEAT TRANSFER REQUIRE THE MOVEMENT OF MATTER

• Yes for convection to work it requires the movement of matter
