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

    Answer:

                    Sample B boils at 102°C. It means that it is an impure sample of water. So it will not freeze at 0°C, but freeze below 0°C. It is noticeable that pure compound (e.g., water) has a sharp melting point.
