उत्तर
The matter is anything that has mass and occupies space. Matter can exist in three states: Solid, liquid, and gas.
- Solid: In solids, molecules are very closely packed, solids are incompressible. They have a definite shape, size, and volume.
Eg: Table, Book, Metals. - Liquid: In liquids, molecules are loosely packed. Hence, liquids are ineligibly compressible. They have a definite volume but no definite shape and size.
Eg: Water, Milk, Petrol - Gas: In gases, molecules are very loosely poked. Hence gases are highly compressible.
Eg: Air, LPG, Oxygen.
