A substance is made up of slow-moving particles that have very little space between them. Based on this information, what can most likely be concluded about this substance?

Gas particles are spread far apart, with large spaces between them. Since the substance’s particles have very little space between them, it is most likely not a gas. Slow movement alone does not determine the state, but the close spacing supports choice C: “It is not a gas because its particles do not have large spaces between them.”
