A high voltage is applied across a sealed vessel containing gas at a very low pressure. If the voltage is high enough, electrons are stripped off the neutral atoms of gas (ionization), forming a current through the vessel. Some electrons recombine with positively charged ions, thereby giving off electromagnetic radiation, while other electrons cause further ionization of neutral atoms. Describe what happens to the pressure inside the vessel when the ionizing voltage is applied.
