Materials required:-
Piston and syringe, Rubber cork,Plain water,Pieces of chalk
Procedure:-
(1)Take three 100 ml syringes and close their nozzles with rubber corks.
(2)Remove the pistons from all the syringes.
(3)Leaving one syringe untouched,fill water in the second & pieces of chalk in the third.
(4)Insert the piston back into the syringes.
(5)You may apply vaseline on the pistons into the syringes for their smooth movement.
(6)Now,try to compress the content by pushing the piston in each syringe.
(7)Record your observations.
Observations:-
(1)In the first syringe,which was left untouched,contains gas(i.e.)the air.It goes freely when pressed because gases have high compression ratio and can move freely.
(2)In the second syringe,which was filled with water allowed little compression.It is because the force of attraction between the molecules are slightly greater than that of gases.
(3)In the third syringe which contained chalk powder,was difficult to compress as the force of atraction between the molecukles and atoms are very very greater than that of liquid and gases.
Inference:-
(1)Solid > Liquid > Gases
