Grade upto college level Modern Physics
Gases begin to conduct electricity at low pressure because
(a) At low pressures gases turn of plasma
(b) Colliding electrons can acquire higher kinetic energy due to increased mean free path leading to ionisation of atoms
(c) Atoms break up into electrons and protons
(d) The electrons in atoms can move freely at low pressures
