Answer :
The key differences between a liquid and the a gas is,
A liquid has no fixed shape but it has a volume.
A gas has neither a fixed shape nor a volume.
A liquid has more inter-molecular space between the molecules.
A gas has larger inter-molecular space between the molecules as compared to the liquids.
- Inter-molecular attraction :
A liquid has some Inter-molecular attraction between the molecules because of the low Inter-molecular spacing between the molecules.
A gas has very low or minimum Inter-molecular attraction between the molecules because of the larger Inter-molecular spacing between the molecules.
A liquid flow from the higher to the lower region but a gas flow in all the direction.

sry bro i didn't understand your question
Answer:
Benzene: 37.5 Torr
Methylbenzene: 12.5 Torr
Explanation:
By Raoult's Law, each substance in a gas mixture contributes to the total pressure of the mixture proportionally to their respective mole fraction. So,
Ppartial = x*P°
Where x is the mole fraction (0.5 for each one because it's equimolar), and P° is the vapor pressure.
Benzene: Ppartial = 0.5 * 75 = 37.5 Torr
Methylbenzene: Ppartial = 0.5 * 25 = 12.5 Torr
