Question

Canal rays obtained from different gases have different mass and charge.Explain.

Answer 1

• Canal rays(anode rays) are streams of positively charged particles which move toward the cathode in a discharge tube when high voltage electricity is passed through a gas at very low pressure taken in a discharge tube.
• The electrons emitted from the cathode collide with the gas atoms found in the tube, knocking out electrons from the atom.
• When electrons are knocked out, atoms get a positive charge.
• As the atoms of different gases have a different number of protons present in them they will have different mass and charge.
• Hence, Canal rays obtained from different gases have different mass and charges.
