How do solids, liquids, and gases differ in shape and volume?
(i) Solids – The intermolecular force of attraction in the solids is very high. So, the atoms are closely packed and do not show any movement. Hence, solids have a fixed shape and a fixed volume.
(ii) Liquids – The intermolecular force of attraction of liquids are higher than gas but less than solids. So, the constituents are less strongly bound by the intermolecular force of attraction. Hence, liquids have a fixed volume but no fixed shape.
(iii) Gases – The intermolecular force of attraction are the weakest in the case of gases. Hence, gases neither have a fixed shape nor a fixed volume.
