H2O Freezing and Melting

Have you ever graphed how a water freezes and/or melts? Have you ever wondered what it looks like? Recently I’ve conducted an experiment to figure it out. 🙂

First, we started out by putting room temperature water into a beaker. We then connected it to a temperature probe to collect the data. Usually  when ice is added to the water, the temperature would first drop, but then it would flatline. Then, the temperature would drop once more and the water would begin to freeze. The same thing happened when you heat the water up. The temperature would first rise, then flatline. Shortly after, the temperature would rise once more and begin boiling.

Our lab went a bit differently. Our melting graph ended up looking like this:

Above, you can see that the ice’s temperature rose and eventually leveled off as the hot water made its effect on it.

While our freezing graph ended up looking like:

This graph shows that the temperature of the water dropped gradually. Then, the temperature flatlined at the point in which the ice met its freezing point.
