Solution

The correct option is B
condensation after vaporisation

To separate a mixture of two or more miscible liquids, distillation (when the difference between the boiling points of liquids is more than $25^{\circ} C$ ) or fractional distillation (when the difference between the boiling points of liquids is less than $25^{\circ} C$ ) are used. In both, the processes the liquid with lower boiling point vaporises and then it is condensed.

So, the volatile liquid undergoes condensation after vaporisation.

A drop each of two non-corrosive and non-irritating liquids A and B at a temperature of $22^{\circ} C$ are placed on the skin. Liquid A gives a more cooling sensation than liquid B. Which of the following can be said about the liquids A and B?

Q. A, B and C are all liquids. Liquid A has a comparatively low boiling point. On heating, liquid A vaporises 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 vaporises 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 CuSO₄ to blue.
