1. what is the difference between the plasma and gaseous states of matter? a. the gaseous and plasma states are electrically neutral b. the gaseous state is electricity positive, while the plasma state is electrically negative. c. the gaseous state is electricity negative, while the plasma state is electrically negative. d. the gaseous state is electrically neutral, while the plasma state can be either electrically positive or negative. 2. how is pressure of a gas related to its concentration of particles? a. pressure will expand a gas, enlarging its volume and reducing its density and concentration of particles. b. pressure will magnify a gas, developing its volume and multiplying its density and concentration of particles. c. pressure will compress a gas, reducing its volume and giving it a greater density and concentration of particles. d. pressure will accelerate a gas, extending its volume and allowing a smaller density and concentration of particles.
