Question 4 • IA-Chemistry A Survey of Chemistry A

What happens as a result of the kinetic energy of the particles in a liquid being comparable with the intermolecular attractions between the particles?

Answer
A
The particles do not move enough to change positions, so the liquid is not compressible.
B
The particles move enough that they separate from one another and take the shape of their container.
C
The particles do not move enough, so they are fixed in place, and the liquid has a fixed volume.
D
The particles move enough that they are not fixed in place, and the liquid can flow.

Explanation

In a liquid, particles have enough kinetic energy to move past one another, but intermolecular attractions still keep them close together. As a result, the particles are not fixed in place and the liquid can flow. Choice B describes gas-like behavior, where particles separate widely.
