How are tstatehe molecules different in each state?

In solids, molecules are closely packed together in a fixed arrangement, resulting in a definite shape and volume. In liquids, molecules are still close but can move past one another, allowing liquids to take the shape of their container while maintaining a constant volume. In gases, molecules are far apart and move freely, filling the entire volume of their container and having no fixed shape or volume. This difference in molecular arrangement and movement accounts for the distinct properties of each state of matter.
