The fact that the water boiled at 102°C instead of the normal boiling point of 100°C suggests that there may be impurities present in the water. This could be due to dissolved substances or contaminants in the water.
As for whether the water will freeze at 0°C, it is difficult to say for certain without more information. The freezing point of water can be affected by impurities, so it is possible that this water may have a different freezing point than pure water. Further testing would be needed to determine the exact freezing point of this particular sample of water.

Is the water pure?
No, the water is not pure. Pure water boils at 100°C at normal temperature and pressure. The boiling point of water increases with the presence of impurities. In this case, the water sample boils at 102°C, indicating the presence of dissolved impurities.
Will this water freeze at 0°C?
No, the water will not freeze at 0°C. The freezing point of water also decreases with the presence of impurities. As the water sample contains dissolved impurities, its freezing point will be lower than 0°C.
Comment:
The impurities present in the water sample may be dissolved salts, minerals, or organic compounds. These impurities can affect the physical properties of water, such as its boiling point and freezing point. The extent of these changes depends on the concentration and nature of the impurities. In general, higher concentrations of impurities will lead to greater changes in the boiling point and freezing point of water.
