Freezing and Melting of Water

Freezing and Melting of Water

If salt is put into ice water, then the water will freeze, because salt expands the freezing water causing more ice or cold water. When the freezing water is put into the warm water, it will melt.





<-- This shows how the water starts to freeze









This graph shows how the water freezes over time. As seen, the huge peak is shown after the water has become frozen. The water’s freezing point was -3.5.

This graph shows how the water melts over a period of time. The huge peak is when the frozen water is put into the hot water. The water’s elting point was1.6.

In the end, I accepted my hypothesis. The water became frozen while in the freezing water, and it melted after being put into the warm water. A problem that occured with our expirement was that we were stirring the salt, however we did not stir enough to make the salt fully dissappear. Some variables that could have differed this lab would have been putting a different amount of water in the water and putting a different amount of water in the test tube and beaker.
