The particles are in contact with each other but can move about at random, so a liquid doesn't have a fixed shape and can flow. 4 of 7 In a gas, how do the particles move? The particles are usually far apart and move at random much faster, so a gas doesn't have a fixed shape and can flow. 5 of 7 Is a gas more or less dense than a solid or liquid?
