Density of plasma<density of air?

Question

I mean the plasma found in the sun and possibly in the rings of saturn. The particles move quickly in such a plasma, so could they give an illusion of density?

Answer 1

Look back at the definition of matter. Anything that takes up space (however small it may be) and has mass.

If plasma is matter, that means it takes up space (aka has volume) and has mass.

So all matter has density. Its not an illusion. Its what it is. I would imagine something that has as high of an energy as the sun, would have a very low density, but it would definitely have a density.

Answer 2

Density by definition is mass over volume. Since plasma is just superheated matter (which takes up a certain volume), and all matter has mass, it is reasonable and logical to say that plasma definitely possesses a density.

As for whether the density of the plasma of the sun is more than that of air, wikipedia states that the average density of the sun is 1400 kg/m3. This is a lot more than that of air.

Hope it answers your questions.
