Question

An activity to show that Compressibility of a liquid is higher than that of a solid but much smaller as compared to the compressibility of a gas

Answer 1

MATERIAL REQUIRED- Syringe (100ml , two) , rubber cork.
PROCEDURE:
(a) Try to push the piston into both the syringes with almost equal force.See what happens.
(b) Insert a nozzle in each syringe into a rubber cork.
(c) Pull out the piston from both the syringes
.(d) Fill one with water . Let other one have water inside it.
(e) Insert piston in both the syringes.
OBSERVATIONS
The piston can be easily pushed inside the syringe that contained it.The piston in the syringefilled with water cannot be pushed inside
.CONCLUSION
Gases are highly compressible.Liquids are slightly compressible

Answer 2

Answer:

Take three 100 ml syringes and remove their pistons. Also, close the nozzles of the syringes with rubber

corks. Then, fill one syringe with chalk powder and the other with water. Now, insert the pistons back into the syringes and push them.

You will observe that the pistons of the syringes (containing chalk pieces and water) require a large

amount of force, while the piston of the third syringe is comparatively easier to push. Hence it

shows that gases are highly compressible.
