Distinguish between three states of matter solid, liquid, and gas on the basis of their molecular model.
Solid | Liquid | Gases |
1. A solid has a definite shape and definite size | 1. A liquid has definite volume but not definite shape. | 1. A gas has neither definite volume not a definite shape. |
2. The molecule in a solid are closely packed. | 2. The molecules in a liquid are loosely packed. | 2. The molecules in a gas are wide apart. |
3. The molecules in a solid fix at their positions they can only vibrate about their main positions | 3. The molecules in a liquid can move within the boundary of the liquid | 3. The molecules of a gas can move freely in space. |
4. The intermolecular forces are very strong. | 4. The intermolecular forces are less strong. | 4. The intermolecular forces are weak |
5. The molecules in a solid are closely package their force solids are highly rigid. | 5. The molecules in a liquid are less closely package there for liquids are less rigid. | 5. The molecules in a gas are loosely package there for gas are non rigid. |
