$A, B$ and $C$ are all liquids. Liquid $A$ has a comparatively low boiling point. On heating, liquid a vaporizes completely without leaving behind any residue. Liquid $A$ is being used increasingly as a fuel in motor vehicles either alone or by mixing with petrol. Liquid $B$ has a very high boiling point. It also vaporizes completely on heating, without leaving any residue. Liquid $B$ is a conductor of electricity and used in making thermometers. Liquid $c$ has a moderate boiling point. On heating, liquid $C$ vaporises leaving behind a white solid $D$ which is used in cooking vegetables. The condensation of vapours from $C$ give a liquid $E$ which turns anhydrous $\mathrm{CuSO}_4$ to blue.
