WGU Integrated Physical Sciences (C165, C908) Exam - Topic 2 Question 12 Discussion

Posted by Caren on May 26, 2026 at 06:05 PM

In which state of matter are particles closest together?

Suggested Answer: B

In the solid state of matter, particles are closest together. This is due to the fact that solids have a definite shape and volume, meaning the particles are tightly packed in a fixed, orderly arrangement. In comparison:

Liquids have particles that are close together but not in a fixed position, allowing them to flow.

Gases have particles that are far apart and move freely.

Plasma consists of ionized particles and is not typically considered in the context of ordinary matter states at standard conditions.

I think it's solid because the particles are packed tightly together, right?
