Final answer:
Liquids have a definite volume but no definite shape, as they conform to the shape of their container.
Step-by-step explanation:
Liquids exhibit all these properties except definite shape. While liquids do have a definite volume, they will take on the shape of their container. This is because the particles in a liquid can move past each other freely, which allows the liquid to conform to the shape of its surroundings. Liquids are much less compressible than gases because the molecules or atoms are closely spaced. The compressibility of liquids is negligible, as their particles are tightly packed with little empty space in between. Slow diffusion is also a property of liquids, although they diffuse more slowly compared to gases due to the closer proximity and stronger intermolecular forces between their particles.
