In given picture , He has 8 molecules.
Since nitrogen is diatomic (N2), 4 pairs of molecules must be present in the picture.
Picture I represents 4 pairs of molecules.
Therefore,
Ans = B

Given that T1 = 25oC = 25 + 273 K = 298 K
V1 = 10 L
T2 = 50oC = 50 + 273 K = 323 K
V2 = ?
According to Charles law,
V1/T1 = V2/T2
10 L/298 K= V2/323K
Then, V2 = 10.8 L
Therefore,
ans = B

CCl4 is non-polar molecule.
The strongest intermolecular force in CCl4 is London disperson forces.

Boiling point is inversely proportional to vapor pressure.
Boiling point order is H2O > CH3OH > CH3OCH3> CH3CH3
Hence,
vapor pressure order is CH3CH3 > CH3OCH3> CH3OH> H2O
Therefore,
ans = A - I > II >IV >III
