Why do YOU think the sun's corona is millions of degrees while the surface is in the thousands?

    The corona is subjected to the intense magnetic field of the sun. Think of it like an iron rod that is repeatedly twisted. The part being twisted will go hot as you will notice.

    The Sun's corona is in a plasma state, wheras the "surface" is gaseous. One possible reason of the corona's high temperature is the intense magnetic field.

    Light travels faster in the Corona. It is hard for light to travel through the inner sun because there are so many protons, atoms, and molecules being created. But in the Corona not much is being created.

    PS- This works because light = heat, and when light is traveling it creates more energy which is used to make more heat.

    Temperture is messured by the movment of molicues.

    The fast they move the higher the temp ;

    The corona is less restrictive to movement so it is hotter.

    It's most likly because space is extreamly cold so the cold cools down the out side of the sun before the inside

    The center has more pressure, which causes more friction which causes more energy which cause heat. The surface is less condensed and more layered which allows energy, i.e., heat, to escape.

    Like any celestial body it's from gravitational pressure.
