Question

a sample of water under study was found to be boil at 102 degree Celsius at normal pressure is the water pure will this water freeze as zero degree celsius comment​

Answer 1

The boiling point of pure water is 1000C. Soluble impurities increase the boiling point of a liquid. As the sample of water boils at 1020C, hence it is not pure. Impurities does not affect the freezing point, hence the given sample of water will freeze at 00C.
