1.The flusoscent tubes and neon sign bulbs glow because ofA) high applied voltageo high temperatureD) high density of gasesB) presence of charged particles​

Answer»

Answer: B) presence of CHARGED particles​

Explanation: When an application of high voltage is provided to the electrodes, the neon gas ionizes DUE to the flow of electrons which thereby excite the neon gas ATOMS and cause them to emit light. In the case of fluorescent tubes, low-pressure mercury VAPOUR is present which EMITS UV light when ionized.
