$A$ sample of water under study was found to boil at $102\,^{\circ}C$ at normal temperature and pressure. Is the water pure? Will this water freeze at $0\,^{\circ}C$? Comment.

(N/A) The boiling point of pure water is $100\,^{\circ}C$ at $1 \text{ atm}$ pressure.
Since the given sample boils at $102\,^{\circ}C$,it indicates the presence of impurities (solutes) in the water.
Therefore,the water is not pure.
Due to the presence of impurities,the freezing point of the water will be depressed,meaning it will freeze at a temperature below $0\,^{\circ}C$.
