Which of the following is true of gases? Gases are not easily compressed because of expansion and limited space between particles. Gases mix easily because of their high kinetic energy and low intermolecular forces. Gas particles diffuse easily because of their low fluidity and high intermolecular forces. Gas particles spread out to fill a container because of their high density and high kinetic energy.
