Detailed explanation-1: -A solid has both definite shape and fixed volume. Liquid has no definite shape, but has a fixed volume. A gas has neither a definite shape nor a fixed volume.

Detailed explanation-2: -Gases do not have a definite shape or volume because the molecules in gases are very loosely packed, they have large intermolecular spaces and hence they move around. The force of attraction between molecules is also very less, as a result gases acquire any shape or any volume.

Detailed explanation-3: -(c) Gases do not have a definite shape or volume because the molecules in gases are very loosely packed, they have large intermolecular spaces and hence they move around. The force of attraction between molecules is also very less, as a result gases acquire any shape or any volume.

Detailed explanation-4: -gas: indefinite shape, indefinite volume. Indefinite shape means that the sample in question takes on the shape of the container.
