Everything, living or not, that has mass and volume is matter.

In the gas state, the particles have complete freedom from each other: the particles are constantly in motion, colliding into each other and the container walls. In the gas state, there is a lot of empty space between the particles: because there is a lot of empty space, the particles can be squeezed closer together.
