of a substance depends on pressure and temperature Solids have a definite volume and shape. The attraction between the molecules is very strong. Liquids have a definite volume but no fixed shape. The attraction between the molecules is less strong than in solids. Gases have no definite volume and shape. Gases will take the shape of the available space and will form homogeneous mixtures.
