    Heat an iron ball to red hot, put it in a glass bowl, how is the heat radiating out?

    Are the electrons in the iron bar change orbitals and emit photons?

    Are the iron atoms vibrating and radiating out gravitational vibration?

    If you have any problems in understanding simple explanations then I suggest a problem/s may be present

    The answer is the same as the other 20 times you asked the same question. No.

    You are so tiring and boring.

    Your post has been reported for trolling.

    You have asked this question in various forms several times... you have been given the answer several times, as well as shown how to find it yourself. You are trolling at this point

    Part of the heat leaves the iron ball as photons, which propagate out into space, carrying some energy away. Part of the heat is transferred to the air and to the glass bowl by conduction - i.e. direct contact between the vibrating atoms in the ball and in the bowl/air. Part of the heat is carried away by convection - air atoms near the ball are heated by conduction and they then rise up - the motion carries heat away.

    So, the short answers is: radiation, conduction, convection.

    Yes.

    Yes, but the energy lost this way is utterly negligible compared with the processes I've already mentioned.
