Question

A definite volume, but not a definite shape, is a property of
A ) solid
B ) liquid
C ) gas
D ) all of the above

Answer 1

Hint: Consider the characteristic properties of each state, solid, liquid and gas and compare how constituent particles are arranged in all three states of matter.

Complete answer:
> In a liquid state, the atoms/molecules have sufficient energy to partially overcome intermolecular interactions. These atoms/molecules can move about each other, but they remain in contact. Hence, liquid state is characterized with definite volume. But atoms/molecules are free to move about each other. Hence, liquid state does not have a definite shape. The liquid takes the shape of the container in which it is placed. Thus, when water is placed in the bucket, it takes the shape of the bucket. But if the same water is now transferred to an earthen pot, it takes the shape of the earthen pot.
> No definite volume, and no definite shape, is a property of gaseous state. A gas takes the shape and volume of the container. A definite volume, but not a definite shape, is a property of liquid state. A definite volume, and a definite shape, is a property of solid state. Even if the containers are changed, the shape and volume of the solid remains the same.

Hence, the option B ) liquid is the correct answer.

Note: Volume of a liquid is definite. It depends on the mass of the liquid and the density of the liquid. Since the density of liquid changes with temperature, the volume of the liquid also changes with the temperature.
