Question

Give an activity to show that solids are incompressible,liquids are only slightly compressible while gas is highly compressible

Answer 1

fill one piston with chalk dust, the other with water and the third with air. you will see that its very hard to push the piston in the syringe filled with chalk, the water can be slightly pushed and it is the easiest to push the piston in air showing that the compressibility of air is greater than water greater than solid
