    Re: Quick Quiz.

    What’s with question 2?

    If iron on the surface of the sun would boil, then isn’t it a liquid?
    Your question asked which is NOT a liquid, how can that be the correct answer?

    Thank You!

      Iron boils at a much lower temperature than the surface of the Sun. So iron on the Sun is a gas, or maybe even a plasma (I’m not sure which). Iron will not stay a liquid on the Sun for long.
