WebHeat Transfer Methods Heat transfers in three ways: Conduction Convection Radiation Conduction When you heat a metal strip at one end, the heat travels to the other end. As you heat the metal, the particles vibrate, these vibrations make the adjacent particles vibrate, and so on and so on, the vibrations are passed along the metal and so is the ...
