Here's why:

* Atoms and molecules in constant motion: Like gases, liquids have atoms and molecules that are constantly moving and bumping into each other.

* Limited freedom of movement: Unlike gases where molecules move freely, in liquids, the molecules are close together and have limited freedom to move around. They can slide past each other, but they are not able to move freely throughout the entire space like gas molecules.
