Compressibility

Which of the following is least compressible?

Why are gases highly compressible ?

Substances in this state are non-compressible :

Fluid is compressible / non compressible.

Solids are least compressible but gases are most compressible. Why?

Give reason Solids cannot be compressed, but gases are highly compressible.

Give an example for a compressible substance .

Liquids and gases can be compressed , but it is difficult to compress solids.Why ?

The ratio of the relative rise in pressure for adiabatic compression to that for isothermal compression is
