What type of heat transfer is this? Conduction, convector, or radiation?

  1. Jan 28, 2013 #1
    We have a pan that is used to boil water. There are 2 surfaces to the pan. One is touching the water and the other is touching the stove, obviously. We have heat that is transferred to to pan's bottom.

    I know what all 3 are and process of elimination tells me this is conduction.
    Is it conduction because the heat transfer is through a medium where each surface of the pan is at a different temperature?

    Convection is also heat transfer through a medium between regions of different temperature. Why is this different from convection?

    Convection involves a fluid flowing through a surface. This generates a velocity profile that starts at 0 velocity at the surface (no slip condition) and gradually increases to the free stream velocity at the boundary layer's exit.
