Gases typically have a much lower density than liquids of the same substance.
Which statement explains this difference?
The particles in a gas have a much smaller mass than the particles in a liquid.
The particles in a gas are much larger than the particles in a liquid.
The average distance between particles in a gas is much greater than in a liquid.
Particles in a gas exert stronger attractive forces on each other than particles in a liquid.
