Particles in a plasma experience collisions than particles in a solid. based on their state of matter alone, is it easier to speak of the shape of the sun or the moon? two unknown substances are in identical beakers. one is a solid and the other is a plasma. if you were given a scale to allow you to obtain the mass of the substance, and had to guess based on mass alone, you would say that the plasma is in the beaker.

Particles in a plasma experience more collisions than particles in a solid.

Based on their state of matter alone, is it easier to speak of the shape of the Sun or the Moon?   moon

Two unknown substances are in identical beakers. One is a solid and the other is a plasma. If you were given a scale to allow you to obtain the mass of the substance, and had to guess based on mass alone, you would say that the plasma is in the lighter beaker.

in the analysis of systems that involve fluid flow, we frequently encounter the combination of properties u and pv.
