A sample of water under study was found to boil at 102°C at normal temperature and pressure. Is the water pure? Will this water freeze at 0°C? Comment.

Answer:

  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 below 0°C as it has impurities dissolved in it.
