Question

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

Answer 1

We know that the boiling point of pure water is 100 degree celcius . Thus if a sample of water at normal temperature and pressure boils at 102 degree Celcius , then it is not pure. Also, since the given sample is not pure, therefore it will not freeze at 0 degree Celcius (freezing point of pure water) but at a lower temperature.
