Answer: The particles of plasma are charged while gases are uncharged
The particles of plasmas have higher kinetic energy than the particles of gases.
Explanation: Gases and plasmas have some similar characteristics on their molecules, they are spread out and occupies a greater volume. For plasmas they are charged molecules of gases. Plasmas have charged molecules or ions compared to a neutrally stable molecules of gases. Plasmas also have extremely higher kinetic energy on its molecules as compared to gases, since plasmas reaches to highly extreme temperatures which makes its molecules move at a greater rate.
