Statement 2: The volume occupied by solid and liquid is too less in comparison to volume occupied by gas.

• A. If both Statement 1 and Statement 2 are true and the . statement 2 is the correct explanation of the statement 1 .
• B. If both Statement 1 and Statement 2 are true but statement 2 is not the correct explanation of the statement 1 .
• C. If Statement 1 is true but Statement 2 is false.
• D. If Statement 1 is false but Statement 2 is true.

Answer 1

Answer: (A)

Statement 2 is the correct explanation for statement.
$\Delta S_{\text {vap }}=S_{\text {vap }}-S_{\text {liq }}$ and $\Delta S_{\text {fus }}=S_{( L )}-S_{( S )} \Delta S_{\text {vap }} > > \Delta S_{\text {fus }}$.
Gaseous states has more disordered system.
