Particle Size Gas particles are small and far apart. There are no significant attractive or repulsive forces between them. Particle Motion Particles are in constant, random motion. They move in straight lines until they collide. Collisions are elastic (no kinetic energy is lost). Particle Energy Mass and velocity determine the kinetic energy of the particle. […]
