Statement I : Whipped cream is a foam whereas hair cream is a gel
Statement II : Gold sol is a multimolecular colloid whereas sulphur sol  is a macromolecular colloid

Whipped cream – foam – ${\mathrm{N}}_2\mathrm{O}$  dispersed in  water  

Hair cream – emulsion – liquid in liquid.
Gold sol and  Sulphur sol – multimolecular colloids

Multimolecular colloids are formed when large number of atoms (or) small molecules of a substance aggregate together to form a species having size in the colloidal range.
