Question

a sample of water under study was found to boil at 102 at normal temperature and pressure. Is the water pure ? Will this water freeze at o c?

Answer 1

well the boiling point of water is hundred degree Celsius
we all know that is soluble impurities increases the boiling point of water
here the sample which is taken boils at 102 degree Celsius from where we can conclude that water was not pure
and we also know that impurities does not affect the freezing point of water
so the water will easily freeze at zero degree celsius
