After reading the lab, create your own purpose below:
When heat is added to ice, it will melt to liquid water. As water is heated, its temperature rises. Eventually, the water will boil and change into gaseous steam. The substance has now gone through two phase changes. The temperatures at which these phase changes occur are important characteristic properties. The relationship between the heat energy and the behavior of the substance is also important in understanding the difference between heat and temperature. In this lab, you will discover the relationship between heat energy and phase changes.
