A sample of water under supply was found to boil at `102^(@)C` at normal temperature and pressure. It the water pure ? Will this water freeze at `0^(@)C` ? Comment.

Text Solution

Verified by Experts

No, the water is not pure. It is because, the boiling point of pure water is `100^(@)C` but the given sample boils at `102^(@)C` . It indicates that it has some dissolved impurities.
No, the water, will not freeze at `0^(@)C` Instead it will freeze it will freeze below `0^(@)C` as it has impurities dissolved in it.
