The solid will keep it's shape and volume.The liquid's volume will stay the same,but it will change to form the shape of the bottom of the container.The gas will change it's volume by filling the container
Explanation:
Solids have a set form and occupy a set volume.
Liquids, as a result of they flow, will occupy no matter form their instrumentation has, so that they don't have a set form. As a result of the particles in liquids are terribly approximate (barely any apart than in solids) liquids don't simply compress, thus their volume is fastened.
Gases can even flow, thus occupy the form of their whole instrumentation. they are doing not have a set form.
