Question

a sample of water under study was found to boil at 102degree celsius at normal temperature and pressure is this water pure ?will this freeze at0 degree Celsius​

Answer 1

Answer: Water is not pure, it will not freeze at O∘C.

Explanation:

The boiling point of pure water is 100∘C at 1atm. The freezing point of pure water is O∘C. The sample of water under study boils at 102∘C at normal pressure. Hence, the sample is not pure water. Since the sample of water is not pure, it will not freeze at O∘C. It will freeze at a temperature below O∘C
