Dual Nature of Radiation and Matter

  1. Gases begin to conduct electricity electricity at low pressure because​​
    1. at low pressures gases turn of plasma ​
    2. colliding electrons can acquire higher  kinetic energy due to increased mean free path leading to ionisation of atoms ​
    3. atoms break up into electrons and protons ​
    4. the electrons in atoms can move freely at low pressures
Correct Option: B

The ionisation requires high energy electrons.
