Name the three states of matter and define them.
(1) 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.
(2) 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.
(3)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.
