Which state of matter doesn't have a definite volume and occupies space?
Correct answer: C. Gases
- A. Solids
- B. Liquids
- C. Gases
- D. All of these options are correct
Explanation
Option A: Properties of Solids:Solid has a fixed shape and a fixed volume.Solid cannot be compressed.Solids have a high density.Force of attraction between the particles in a solid is very strong.The space between the particles of solids is negligible.Option B: In a liquid, the particles are still in close contact, so liquids have a definite volume. However, because the particles can move about each other rather freely, a liquid has no definite shape and takes a shape dictated by its container.Option C: Gases have three characteristic properties: (1) they are easy to compress, (2) they expand to fill their containers, (3) they occupy far more space than the liquids or solids from which they form

The more specific you are, the faster it gets fixed. A source beats an opinion.

About Kinetic Molecular Theory
Kinetic molecular theory explains gases as rapidly moving particles separated by large distances, with negligible volume and negligible intermolecular attraction in the ideal model. It relates temperature to average kinetic energy and explains gas pressure, Boyle's and Charles's laws, diffusion, effusion and the conditions under which real gases deviate from ideal behavior.
