Describe the arrangement, movement and energy of the particles in a gasParticles are far apart and there are no forces between them. Energy is high. The particles move quickly and freely.Particles are close together and regularly packed. Energy is high. Particles are free to move and moving moderatelyParticles are close together and regularly packed. Energy is low. The particles vibrate around a fixed point. Particles are far apart and there are no forces between them. Energy is high. The particles vibrate around a fixed point. Question 3 of 12 Loading... 4.
