3 Forms Of Heat Transfer. Conduction convection and radiant heat often referred to as radiation but thats a more general term that includes many other phenomena. It always flows from a region of high temperature to a region of low temperature ie.
From hot to cold. Heat can travel from one place to another in several ways. Radiation convection and conduction.
Radiation can transfer heat even in a vacuum where conduction and convection cannot take place.
Radiation conduction convection radiation radiation is heat that can be transferred between two areas without any contact to the heat source. In general heat flows from here to there by three distinct mechanisms. You can feel the suns warmth on your skin even though you are not touching it that is radiant heat transfer. Therefore here are the three modes of heat transfer.
