In my own view, if a gas must conduct electricity, it must do so on some certian conditions. A gas in a discharge tube will only conduct electricity through it, if high voltage is applied at the two terminals of the tube and that must be done maintaining the pressure of the gas at a low pressure. The colour of the glow in the tube depends on the nature of the gas inside the tube.
If the pressure of gas in the tube is continously lowered to the extent that there less molecule to ionize and cause flourecence in the tube,
then the stated conditions such as:
