    Could a good conductor, like some metal, be heated past the temperature of the heat that's heating it. Like if I use a 100 degree flame and hold it for hours on some piece of metal, could the metal go above 100 degrees?

    And I'm not talking about special cases. I mean does this generally happen?

    No. Fourier's law prevents heat flow from a lower to a higher temperature

    No. If the metal was hotter than the flame which way would energy flow?

    Aside: A heat pump can be used to move energy from a cold place to a hot place.
