On the basis of the kinetic theory of matter . explain why. (a) solid have a fixed shape and fixed volume. (b) liquid have a fixed volume but not a fixed shape |

Answer» rticles do not have ENOUGH kinetic energy to overcome the force of attraction between them, matter exists as a solid. The PARTICLES are packed closely together and held rigidly in place. All they can do is vibrate. This explains why solids have a fixed volume and a fixed shaped2.Why the liquids have a definite volume and but no definite shape? Liquid molecules are also packed closely together, but there is enough space between the molecules to allow them to SLIDE past each other. This sliding action PREVENTS the liquid from TAKING a shape of its own. |
