Difference Between Conduction And Convection Of Heat. Heat transfer is the physical act of thermal energy being exchanged between two systems by dissipating heat. Radiation does not require physical contact between two objects like the other methods.
Heat transfer is the physical act of thermal energy being exchanged between two systems by dissipating heat. The main difference between convection and conduction is that in convection heat is transferred through a mass flow of material while in conduction heat is transferred through collisions of particles that make up the material. While both conduction and convection are means of transferring heat the important difference is the medium through which the heat travels.
Convection-cooling is sometimes loosely assumed to be described by Newtons law of cooling.
In conduction this happens through direct physical contact between two objects. It can take place between objects only by direct contact between them. Energy is transferred from the warmer object into the colder object until the temperature of both objects is exactly the same. In conduction this happens through direct physical contact between two objects.
