Compressibility decreases in the order:
AGas > liquid > solid
BSolid > liquid > gas
CLiquid > solid > gas
DGas = liquid = solid
Answer & Solution
Correct answer: A. Gas > liquid > solid
1. Gases have large inter-particle spacing and can be squeezed greatly.
2. Liquids have particles closer together and resist much more.
3. Solids have particles in fixed positions and are nearly incompressible.
4. So compressibility is highest in gases and lowest in solids.
5. The order is gas > liquid > solid.
