Friction is a great example of which type of heat transfer?

Friction is not an example of heat transfer. Friction creates the heat. The heat created by friction can get transfered to the surroundings by all three types of heat transfer depending on what two surfaces or median that is creating the friction.|||conduction|||Conduction, but it may also have convection, if there is a moving fluid with different temperature around such as air.|||Friction is a great example of heat and light propagation IE.. heat produce by bearing surfaces, light emitting diode (LED) works on friction. While heat transfer can be manipulated by solid materials (conduction) , by air (convection), and liquid.
