Question

A sample of water under study was found to boil at 102 degrees celsius at normal temperature and pressure is the water pure? Which water freeze at zero degree celsius? Comment

Answer 1

No. The water is contaminated with some impurities . Pure water has its boiling point at 100·C and freezing point at 0·C .

Answer 2

Answer:

Sample 'B' will not freeze at 0°C because it is not pure water. At one atmospheric pressure, the boiling point of pure water is 100°C and the freezing point of pure water is 0°C.
