Question

Differentiate between solids, liquids, and gases on the basis of their properties.

Answer 1

Differences between the characteristics and properties of solid, liquid, and gases are given in the below table.

Sl.No	Characteristic property	Solid	Liquid	Gas
1	Arrangement of molecules	Solids exhibit a definite shape where particles are arranged in a specific pattern.	Molecules are arranged loosely so that it does not have a definite shape.	The molecules are arranged more loosely than liquids so it does not have a definite shape.
2	The intermolecular force of attraction	The Intermolecular force of attraction is greater in solids.	The intermolecular force of attraction is lesser than solids.	The intermolecular force of attraction is very poor in gaseous molecules,, they are in random motion.
3	Intermolecular space	The Intermolecular space in solid is less due to the closely packed arrangement in molecules.	The Intermolecular space in liquid is greater than in solids because the molecules are packed loosely.	The Intermolecular space in gas is greater than in solids and liquids.
4	Volume	Solids have a definite volume.	Liquids have definite volume.	Gases do not have a definite volume.
5	Compressibility	Solids cannot be compressed because they may be already compact.	Liquids are compressible to a little extent.	Gases are easily compressible.
6	Examples	Ice, wood, glass.	Water, oil, milk.	Carbon dioxide (CO2), water vapor, and hydrogen (H2) gas.
