Detailed explanation-1: -A solid has a definite shape and volume as the interparticle forces of attraction are highest as compared to liquids and gases. The shape and volume do not vary as in the case of liquids and gases.

Detailed explanation-2: -Solids have a definite volume and shape because particles in a solid vibrate around fixed locations. Strong attractions between the particles in a solid restrict their motion, keeping them in place.

Detailed explanation-3: -Solids have a definite shape and definite volume. This means the shape of the material does not change, and it can’t be compressed. Liquids do not have a definite shape, but have a definite volume. This means that a liquid will take the shape of whatever container it is in, but the liquid can’t be compressed.

Detailed explanation-4: -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. The change from solid to liquid usually does not significantly change the volume of a substance.

Detailed explanation-5: -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.
