SUMMARY
Hot plasmas are characterized by high temperatures and fast-moving ions, while cold plasmas exhibit lower temperatures and slower particle velocities. Examples of hot plasmas include the ionosphere and lightning, whereas cold plasmas can be found in polar aurorae. The temperature of a plasma is determined by the root mean square (rms) velocity of its particles, establishing a clear distinction between the two types based on their thermal energy.
