Question 48 • Liberty - Physics A
A plasma contains charged particles, while the particles in an ordinary liquid are generally neutral, so particle charge helps distinguish them. Liquid particles are close together and liquids are difficult to compress; a plasma is much less dense, so its particles are farther apart and it is more compressible. Mass, container shape, and color do not reliably identify whether a substance is a liquid or a plasma.
