$CO_2$ has no lone pairs on the central atom, while $SO_2$ does.

$CO_2$ has double bonds, while $SO_2$ has single bonds.

$CO_2$ has a smaller steric number than $SO_2$.

$CO_2$ forms tetrahedral bonds, while $SO_2$ forms trigonal planar bonds.

One-phase system

Two-phase system

Homogeneous mixture

Solution

Gas has a definite shape.

Gas has no definite shape.

Gas has no definite volume.

Gas fills its container completely.

Vaporization involves breaking all intermolecular bonds, while fusion only weakens them.

Water molecules are larger in the gaseous state than in the liquid state.

The temperature for vaporization is much higher than for fusion.

Fusion is a slower process, allowing more time for energy absorption.

Difference in partial pressure

Sum of partial pressures

Product of partial pressure

Average of the partial pressures
