Answer 2

Answer:

Correct Answer: C

Explanation:

Correct Answer: C. A gas has a changeable shape and will expand or shrink to fill any container.

Explanation: A gas has a changeable shape. You can see this when a gas takes the shape of the container it is put in. A gas can expand or be compressed to fill any container, no matter how large or small the container is.

A fixed shape with the same volume in any container (choice B) describes a solid, while a changeable shape with the same volume in any container (choice D) describes a liquid. Choice A does not correspond to any known phase of matter.
