Answer 1

1. Sublimation is a process in which solid changes directly into vapour state without undergoing liquid state with the absorption of heat energy.
2. Ammonium chloride (NH₄Cl) can be separated from the mixture of the common salt by the method of sublimation as ammonium chloride(NH₄Cl) is a sublimable substance whereas common salt is non-sublimable. Therefore sublimation is the correct answer to be filled in the blank.
