Question

what is the difference between plasma and gas

Answer 1

⏺Plasma is ionised gas.
⏺Unlike gas, it does not exist in free state in nature.
⏺Plasma just like gas is another state of matter.
⏺It can be generated by heating or subjecting a neutral gas to a strong electromagnetic field to the point an ionised gaseous substance becomes increasingly conductive, and long-range electromagnetic fields dominate the behaviour of the matter.
