Question

A sample of water under study was found to boil at 105 c at normal temperature and pressure is the water pure or not will this water freeze at 0 c or not give reason in support of your answer

Answer 1

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.

Explanation:

Answer 2

Answer:

Sample 'B' will not freeze at 0°C because it is not pure water. At one atmospheric pressure, the boiling point of pure water is 100°C and the freezing point of pure water is 0°C.
