Question

You are given two water samples A B. A boils at 100 degrees celsius B boils at 102 degrees celsius. Which sample will not freeze at 0 degreese why?

Answer 1

B sample will not freeze at 0degrees because it will boil early so it's boiling point is 2degree more

Answer 2

It is because sample ‘B’ boils at 102°C while the boiling point of pure water is 100°C. It means this sample contains impurities. Only pure substance has sharp melting point.
