How does the pressure change the amount by which air ionizes? I know that high pressure suppresses ionization. But why?
Concept please!

Pressure is the force applied per unit area on an object. In the context of ionisation, pressure can affect the ionisation process by either increasing or decreasing the likelihood of ion formation. This is because pressure can influence the distance between particles, which in turn affects their interactions and the likelihood of ionisation occurring.
Under high pressure conditions, ionisation can occur through various processes such as impact ionisation and Penning ionisation. In these processes, high pressure causes collisions between particles, leading to the transfer of energy and ionisation of atoms or molecules.
Ionisation energy is the amount of energy required to remove an electron from an atom or molecule. The higher the pressure, the closer the particles are to each other, resulting in stronger interactions and higher ionisation energy. This means that higher pressure can make it harder to ionise particles.
Yes, pressure can affect the stability of ions. Higher pressure can lead to more collisions between particles, which can disrupt the stability of ions and cause them to recombine into neutral atoms or molecules. On the other hand, lower pressure can promote ion stability by reducing the likelihood of collisions.
Plasma is a state of matter in which a gas is ionised and contains a high number of free electrons and ions. Pressure plays a crucial role in creating and maintaining plasma. High pressure can help create plasma by compressing a gas and increasing its temperature, while low pressure is needed to confine and control the plasma without it dissipating.
