Hello, Are there any Plank Radiation Spectrums for liquids? What I really want to know is, for a given liquid, what wavelength of light is emitted for a given temperature. For example, if I journey to the center of the Earth, the molten lava is about a thousand degrees, hot enough to emit red light --> thus, it seems I would not be in a dark abyss if I travel to the center of the Earth but a glowing, red-yellow abyss all around me. Or if I fell into a molten lake of steel, this too would not be dark, but bright yellow (as seen from web page images). I could not find this kind of data on any liquid and guessed this concept would be where exotic matter specialists would be most likely to know.
