GEOLOGY

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: -Volume: Gas is the state of matter that has no definite shape or volume.

Detailed explanation-3: -In gases, the particles are very loosely packed and the intermolecular force of attraction is very weak. So the gas molecules can break loose easily from any boundary and can fill up any space. Hence, they do not have any definite volume.

Detailed explanation-4: -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-5: -A gas has neither a definite shape nor a definite volume. Like liquids, gases are fluids. The particles in a gas can move around one another freely.
