More Answer:
Common properties of Solid:
- A solid has a definite shape and volume.
- Solids in general have higher density.
- In solids, intermolecular forces are strong.
- Diffusion of a solid into another solid is extremely slow.
- Solids have high melting points.
Common properties of Liquid:
- Liquids are almost incompressible.
- Liquids molecules are pretty close to each other.
- Liquids have fixed volume but no fixed shape.
- Liquids flow from higher to lower level.
- Liquids have their boiling points above room temperature, under normal conditions.
Common properties of Gas:
- They are easy to compress.
- They expand to fill their containers.
- They occupy far more space than the liquids or solids from which they form.
- Gases have no definite shape or volume.
- Low Density
