Question

You are given two samples of water labelled as 'A' and 'B'. Sample A boils at 100 degree Celsius and Sample B boils at 102 degree Celsius. Which sample of water will not freeze at 0 degree Celsius?

Answer 1

Answer:

Sample B will not freeze at 0° C.

Explanation:

As sample A boils at 100° C, therefore it contains pure water. However, sample B boils at 102° C, which tells us that there are some impurities in that water, and hence it will not freeze at 102° C.
