Discussion Overview

The discussion centers around the color of liquid carbon at the atomic level, exploring its properties under different conditions such as temperature and pressure. Participants reference phase transitions and the metallic nature of liquid carbon.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • One participant suggests that liquid carbon is probably white due to heat.
  • Another participant describes liquid carbon as a very bright gray or colorless.
  • A different contribution states that liquid carbon is metallic unless the pressure is too low, in which case it becomes an insulator, and proposes that the metallic form should appear silver-colored.
  • A reference to a paper on phase transitions of carbon is provided, but it does not include a spectrum of the color.
  • A link to further discussion on the phase diagram of carbon is shared.

Areas of Agreement / Disagreement

Participants express differing views on the color of liquid carbon, with no consensus reached on a definitive answer.

Contextual Notes

There are limitations in the discussion regarding the lack of empirical data on the color spectrum of liquid carbon and the dependence on specific conditions such as temperature and pressure.

What color of liquid carbon
 
Physics news on Phys.org
Probably white from the heat.
 
is it very bright gray colorless color. ...
 
Here is a paper on the phase transitions solid-liquid-gas for carbon.

Liquid carbon is metallic unless the pressure is too low - then it is an insulator.

The metallic form should appear like most metals: silver colored. They don't provide a spectrum in the paper.
