Examples for plasma

    I have a question about plasma and its temperature:
    Which plasmas are hot plasma and which are cold plasmas.For example ionosphere ,Lightning,polar aurorae etc.

    Sounds like a homework question, so I'll try not to be specific!

    The temperature of a gas or plasma is a bulk property and is related to the rms of the velocity of the individual particles in the system in question.

    So a hot plasma has fast moving ions.
