Distinguish between solids , liquids and gases NAME – VINAYAK KHANNA CLASS - 9C ROLL NO - 37

MATTER : 

MATTER Any thing that occupies space and has mass is called matter. Matter is made up of small particles. On the basis of their physical states , all matter can be classified into three groups : Solids, Liquids and Gases. For examples: Solids: Sugar, iron, wood, ice etc. Liquids: Water, milk, oil, petrol etc. Gases: Air, oxygen, hydrogen, CO2 etc.

SOLIDS : 

SOLIDS In solids, the particles are closely packed. There is a high force of attraction between the particles of solids. They cannot move from one position to other. The inter molecular space is very less in solids. They have very less kinetic energy. They are not compressble. TABLE IS A SOLID.

PROPERTIES OF SOLIDS : 

PROPERTIES OF SOLIDS Ice, wood, stone etc are some common solids we see around us. They have following properties:- They have a fixed shape and fixed volume They cannot be compressed. They have high density. They do not fill their container completely. They have definate boundaries. They are rigid.

LIQUIDS : 

LIQUIDS In liquids the particles are close to each other, but they are not as close as in solids. There is comparatively less force of attraction between particles of liquids than solids. They can move but to some extend. They have a moderate inter molecular space. They have more kinetic energy than solids. They have little compressibility. JUICE IS A LIQUID.

PROPERTIES OF LIQUIDS : 

PROPERTIES OF LIQUIDS Water, milk, ink, juice are some common liquids. They have following properties :- They have fixed volume but no fixed shape . They take the shape of container. They have little compressibility. They have moderate density. They are fluid.

GASES : 

GASES In gases particles are not close to each other. They are very far to each other. They have very less force of attraction. The particles move freely . They have high inter molecular space. They have very high kinetic energy. They are highly compressble.

PROPERTIES OF GASES : 

PROPERTIES OF GASES Air, Oxygen, Carbon dioxide etc are some gases. They have following properties:- They have neither fixed shape nor fixed volume. They are highly compressble. They have very low density. They are fluid.
