Analysis Results

We have deduced that impurities in water such as salt will affect the boiling temperature of water. Although the result will be very slight, we need to add in a lot of impurity to see change, or reduce the amount of water used, which was what we did. The freezing point was also affected, where the temperature dropped significantly , and did not level off. As for the boiling part, the temperature recorded was what we was expecting, where it rose till it reached boiling point.
