Solids are matter having fixed shape, fixed volume and are almost impossible to compress. Of course, solids can be crushed into powder form (in which case the fixed shape is destroyed), but in essence the powder still remains a solid.iquids are matter having a fixed volume but no fixed shape â they take the shape of the container. Liquids are very difficult to compress. Liquids are composed of higher energy particles which overcome their mutual forces of attraction and move independently. This is the reason why liquids do not have a fixed shape.
