. . Difference between solid, liquid and qas 1 2 3 4 Property Intermolecular attraction Density Fluid • Diffusion Solid Molecules are held together by strong intermolecular forces of attraction Solids have very high density does not flow easil very low rate of diffusion Liquid Attractive forces between molecules are intermediate Intermediate density to solids and gases flows esil moderate rate of diffusion Attractive forces between molecules are very weak Possess very low density flows easil molecules display a very high rate of diffusion.
