what are four states, or phases of matter? describe the shape and volume properties of each phase, can they change or are they fixed?

Liquid: no definite shape since it takes the shape of the container, definite/fixed volume since the particles are held close together but not as much as a solid
Solid: definite volume and shape
Gas: neither a definite volume or shape
Plasma: no fixed shape or volume, less dense than solid or liquids

im not 100% sure but i think its false
