Answer 2

Answer:

At high pressure ,the free mean path of the electrons

is quite low..When the gas is pressure low but not too low the electrons. get enough time or distance to accelerate .By the time they collide with an atom ,they have gained enough kinetic energy from the electric field to ionize other atoms
