Select the incorrect statement.

1. The bulk modulus of solids is far greater than that of liquids.
2. Gases are less easily compressed.
3. Solids are nearly incompressible because adjacent atoms are strongly bound to one another.
4. The reciprocal of bulk modulus is known as compressibility.

Correct answer: Gases are less easily compressed.

Solution

The incorrect statement is 'Gases are less easily compressed' - gases are in fact the most easily compressed state because of their large intermolecular spacing. The other statements (high bulk modulus of solids, near-incompressibility of solids, compressibility = 1/bulk modulus) are all true.
