Answer:
Most particles in the plasma are heavy and slow.
Step-by-step explanation:
Hello,
In this case, one must remember that the temperature has a directly proportional relationship with the kinetic energy which is related with the energy content and motion of the molecules composing a system. In such a way, since plasma particles are heavy and slow, the kinetic energy associated with them is low which implies a low temperature as well when using them, in this manner, that low temperature helps plasma based light to be efficient with no high heating unlike traditional ways to produce light with electric energy circuits.
Best regards.
