About Lesson
There are three modes of heat transfer namely conduction, convection and radiation.
Conduction : Conduction refers to the heat transfer that occurs across the medium. Medium can be solid or a fluid.
Convection : Convection refers to the heat transfer that will occur between a surface and a moving fluid when they are at different temperatures.
Radiation : In radiation, in the absence of intervening medium, there is net heat transfer between two surfaces at different temperatures in the form of electromagnetic waves.
