Detailed explanation-1: -Any matter that is a solid has a definite shape and a definite volume. The molecules in a solid are in fixed positions and are close together. Although the molecules can still vibrate, they cannot move from one part of the solid to another part. As a result, a solid does not easily change its shape or its volume.

Detailed explanation-2: -A solid has a definite shape and volume. The particles in a solid cannot move away from or come closer to each other so they are not free to slip over one another. Hence a solid can retain its shape. For the same reason, the volume of a solid is fixed.

Detailed explanation-3: -Solids have a definite shape and volume. Liquids have a definite volume, but take the shape of the container. Gases have no definite shape or volume.

Detailed explanation-4: -In a liquid, the particles are still in close contact, so liquids have a definite volume. However, because the particles can move about each other rather freely, a liquid has no definite shape and takes a shape dictated by its container.

Detailed explanation-5: -(b) Liquids have a definite volume but no definite shape.
