Is the water pure And Will this water freeze at 0°C

By
A sample of water under study was
found to boil at 102°C at normal temperature and pressure. Is the water pure And  Will this water freeze at 0°C? 

Comment. Answer: The boiling point of pure water is 100°C. Soluble impurities increase the boiling point of a
liquid. As the sample of water boils at 102°C, hence it is not pure. 

Impurities does not affect the freezing point, hence the given sample of water will freeze at 0°C .
