Question

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.

Answer 1

Answer:

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
