Detailed explanation-1: -Thus, the correct answer is ‘liquid’. Liquids have a definite volume but no definite shape.

Detailed explanation-2: -Liquids occupy definite volume but have no definite shape. This is because the inter-molecular force of attraction between the molecules in a liquid is less when compared to solids and the liquid molecules are loosely packed. In a liquid, the particles are in close contact and so they have a definite volume.

Detailed explanation-3: -A solid has definite volume and shape, a liquid has a definite volume but no definite shape, and a gas has neither a definite volume nor shape.

Detailed explanation-4: -(b) Liquids have a definite volume but no definite shape.

Detailed explanation-5: -Liquids occupy a fixed volume but no fixed shape. This is because the particles in the liquid state are not packed closely and also arranged disorderly. There are spaces between the particles, that is the particles are bound by loose intra-molecular forces of attraction.
