Here is a chart of all states of matter. All states of matter have a definite mass and all are expandable. Solid has everything as definite and Gas has the most indefinite. Liquids have 2 definite and 1 indefinite and I think this means that materials that have faster moving molecules have a higher amount of indefinite's. This information can conclude to one thing: scientists have done more studying for an element of gas compared to elements of liquid or solid. Also when the Volume, Shape, Mass get more definite, the compressibility decreases. I think this is because the slower the molecules move, the less compressible it gets. Over all I think this was a good experiment because we learnt a lot of things. ( experiment was with the cold water, room temperature water, and the hot water.)
