minimoman Posted September 21, 2011 Share Posted September 21, 2011 Does liquid neon retain its properties of lighting up when a charge goes through it the same way it does when it is a gas? Link to comment Share on other sites More sharing options...
Voltarius Posted September 21, 2011 Share Posted September 21, 2011 I would say yes, because you're only changing its physical state, rather than reacting the element chemically with another element or compound. Though, I could be wrong, so don't run off and do an experiment just based on what I said. 1 Link to comment Share on other sites More sharing options...
Enthalpy Posted September 21, 2011 Share Posted September 21, 2011 Density changes radically the process. The orbital energy levels remain nearly the same, BUT: - The time between two shocks gets tiny, so you won't see any emission lines more. They'll get so broad you can't separate them. - The distance between two shocks gets tiny, so it needs a much stronger field for an electron or ion to acquire the energy needed to ionize an other atom and maintain the spark. - The very concentrated spark vaporizes the liquid locally, making the process unstable. In fact, neon discharge tubes use a low pressure to obtain a stable discharge, not just to permit a 100V or 200V spark over a significant distance (only 1/10mm at 1 bar). Sparks in liquids exist and are used, in electrical discharge machining (see Wiki). Very short distance, very destructive. 1 Link to comment Share on other sites More sharing options...
