Gas

assumes the shape and volume of its container

particles can move past one another

compressible -lots of free space between particles

flows easily particles can move past one another

Liquid

assumes the shape of the part of the container which it occupies

particles can move/slide past one another

not easily compressible little free space between particles

flows easily particles can move/slide past one another

Solid

retains a fixed volume and shape rigid - particles locked into place

not easily compressible little free space between particles

does not flow easily rigid - particles cannot move/slide past one another
