उत्तर
There are three states of matter
- Solid State : The molecules are very close to each other hence intermolecular spaces are small and intermolecular force is strong.
Hence solids have definite volume, rigid, retain definite shape and are incompressible.
- Liquids : The molecules are less closely packed have more intermolecular spaces than solid, less stronger forces than solids.
Hence liquids have definite volume but no definite shape. They take the shape of container in which they are put. - Gases: The molecules in the gases are for apart with weakest force of attraction. Hence gases have neither definite volume nor definite shape and compressible.
- Liquids : The molecules are less closely packed have more intermolecular spaces than solid, less stronger forces than solids.
