Heat Transfer

Conduction,Convection Radiation


Heat energy can move through a substance by conduction.

Poor conductors of heat are called insulators.

Metals are good conductors of heat, but non-metals and gases are usually poor conductors of heat.


Convection occurs when particles with a lot of heat energy in a liquid or gas move and take the place of particles with less heat energy.


In physics, radiation is the emission or transmission of energy in the form of waves or particles through space or through a material

All of these create heat
