Intermolecular distance is the distance between the particles that make up matter. The graph below compares the intermolecular distances in two substances. One substance is gas and the other is a liquid. Which statement best describes the two substances?

A. Particles collide in liquids so Substance Y is a liquid
B. Particles collide in gas so Substance X is a gas.
C. Particles move around in liquids so Substance X is a liquid.
D. Particles move around in gas so Substance Y is a gas.

y has to be a liquid and x would be a gas

Explanation:

the closer two molecules are, greater is the force of attraction which makes them stick together and give it a structure

here y has lesser intermolecular distance so it is a liquid

particles will collide in gas though as

liquid particles have constant motion
