Step-by-step explanation:

Matter exists in three physical states. They are :
✰

- They have fixed shape.
- They have fixed volume.
- They do not flow.
- They cannot be compressed , because their molecules are closely packed.
- They are mostly hard.
[ Stones , bricks etc are some of the examples of solid ].
✰

- They don't have a fixed shape but can take the shape of their container.
- They cannot be compressed.
- They flow from one place to another as their molecular are loosely packed.
- They have fixed volume.
[ Water , Ink , Milk , Cooking oil , petrol etc are some of the examples of Liquid ] .
✰

- They don't have fixed volume.
- They can flow very easily.
- They can be compressed easily.
- They do not have fixed shape as the position of their molecules are not fixed.
[ Air , oxygen , carbon dioxide etc are some of the examples of gas ] .
