Solution
| Property | Solid | Liquid | Gas | |
| 1. | Shape and volume | They have a definite shape as well as a definite volume. | They have a definite volume but no definite shape. | They have neither a definite shape nor a definite volume. |
| 2. | Compressibility | Solids are completely incompressible. | Liquids are almost incompressible. | Gases are highly compressible. |
| 3. | Rigidity/Fluidity | Solids possess rigidity. | Liquids can flow, therefore they possess fluidity which is lower than that of gases. | Gases flow more easily than liquids and thus, have the highest fluidity. |
| 4. | Kinetic energy | Their particles have minimum kinetic energy. | Their particles have kinetic energy higher than those of solids. | Their particles have the highest kinetic energy. |
| 5. | Density | They have high-density. | Their density is lower than those of solids but much higher than those of gases. | They generally have very low densities. |
| 6. | Diffusion | They normally do not show the property of diffusion although some rare examples of diffusion of one solid into another are known. | They show the property of diffusion. As a result, solids, liquids, and gases can all diffuse into liquids. | They diffuse very. The diffusion of a gas is, however, inversely proportional to the square root of its density. Thus, lighter gas diffuses more rapidly than heavier gas. |

The substance X normally exists in a physical state which can flow easily but does not fill its vessel completely. It also turns anhydrous copper sulphate blue. When substance X is cooled excessively, it changes into a substance Y which has a fixed shape as well as a fixed volume. If, however, the substance X is heated strongly, it changes into a substance Z which has neither a fixed shape nor a fixed volume.
