Question

A sample of water under study was found to boil at 102 degree celcius at normal temperature and pressure. Is this water pure? Will it freeze at 0 degree celcius? Comment.

Answer 1

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.
