I was passing time by Googling the properties of the sun (temperature, mass, etc) and got to wondering what lies at the center of stars. I found out its plasma under roughly 340 billion atmospheres of pressure. I realize Boyles law may not be strictly meant for plasmas, but using it I calculated the volume change of 1 cubic foot of air at 340 billion atmospheres to roughly the volume of 93 hydrogen atoms. Since there are roughly 1.52*10^24 atoms in one square foot of air at standard pressure, that many atoms squeezed to such a small volume, would seem to suggest that the plasma would act like a very rigid, very hard solid. Is that the case?
