Question

How canal rays depend upon the nature of gas ...??

Answer 1

Answer:

This is how nature of canal rays depend upon nature of gas.

Canal rays depend upon nature of gas because the origin of canal rays are gaseous ions.

The gaseous atoms present in the glass discharge tube are hit by the cathode rays, which cause the electrons to gain energy and move out of the atom.

Answer 2

Canal rays depend upon the nature of gas in the way that they are produced by the ionisation of the atoms of the gas.

Explanation:

• Canal ray experiment was performed by Goldsteinwhich led to the discovery of protons.
• In this experiment, a discharge tube containing a perforated cathode is taken and then a high voltage is applied.
• The application of the high voltage ionises the gas present in the tube and the circuit gets completed. Thus, electricity starts flowing in the circuit.
• Faint luminous rays are observed to be extending from the holes at the back of the cathode.
• These rays travelled in the opposite direction of the cathode rays.
• These rays are found to depend upon the nature of the gas because they are formed by the ionisation of the atoms of the gas.
• They contain positive ions which are formed when one or more electrons leave the atoms of the ions when subjected to high voltage.
