    Do all incandescent solids obey the fourth power law of temperature?

    I think they all obey \(\ T^4 \)
    But the constants are different for them.

    Agreed?

    What constants?

    The Stefan-Boltmann law is the same for all incandescent bodies.

    Oh man, I am talking about emissivity that multiples to \(\sigma\)

    Yes. Different objects have different emissivities. If they didn't, there'd be no need to include that constant in the Stefan-Boltzmann law...
