There three modes of heat transfe: conduction,convection and radiation, but when we talking about the basics i think the heat by convection is not basic because it is depended mainly on the moving flow

Nooraldeen Alenize

There are three modes of heat transfer : Conduction , Convection , and Radiation : about the basic itis Radiation because Radiation is a form of heat transfer. It does not require any medium and can be used for transfer of heat in a vacuum as well.
