Which of the following is not a physical property of a liquid? indefinite volume indefinite shape definite mass

Option (a) is the correct answer.

Explanation:

When there occurs no change in chemical composition of a substance then it is known as a physical property.

For example, volume, mass, shape, size, density etc are all physical properties.

In liquids, the molecules are held by slightly less strong intermolecular forces of attraction as compared to a solid. So, the molecules of a liquid are able to slide over each other as they have kinetic energy.

Therefore, a liquid has indefinite shape because they acquire the shape of container in which they are placed. But a liquid does not have a definite volume.

Thus, we can conclude that indefinite volume is not a physical property of a liquid.
