Which of the following describes a liquid?

• molecules can move around each other, but not away from each other. Changes shape with container.

• keeps its shape because molecules only move in place, not around each other.

• no visible shape because molecules can move away from each other.

• molecules can flow freely inside of the container but not beyond that
