Convection is actually a combination of conduction and mixing in which molecules in a fluid move from a warmer area to a cooler one. 2. Toasting and broiling are two cooking methods that rely on infrared heat because radiant heat waves travel at the speed of light in any direction. 3.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
