Sarah was studying phase change in science class. She believed that cold water would begin boiling sooner than warmer water. Sarah and his father did the following investigation
Hypothesis The lower the water's starting temperature, the quicker the water will start to boil.
Experimental Design Sarah and her dad used three different water temperatures. They measured 50 ml of water into 100 ml beakers. The temperature
of the water was recorded. They placed the beakers in a large pan of water and placed the water on the burner of the stove. Sarah timed how long it
took each container to boil. They also ran the experiment three times and took an average of their data. You can see the data in the table above.
