A) at low pressure, gases turn into plasma
B) colliding electrons can acquire higher kinetic energy due to increased mean free path leading to ionisation of atoms
C) atom breaks up into electrons and protons
D) the electrons in atoms can move freely at low pressure
Correct Answer: B
Solution :
At low pressure, the electrons acquire sufficient kinetic energy under the applied potential difference, which can cause ionisation by collision with atoms, which results in the availability of number of ions.
