Identify . the boiling and freezing/melting points of water on the Celsius scale. . STAAR 2013 #14; RC 1; Supporting; 47. 1. A student measures the temperature of water being heated on a hot plate. The student observes that the temperature of the water is 53ºC. How many more degrees Celsius must the temperature rise before it reaches the boiling temperature of water?. The heating curve is a graph which represents how a sample changes phases. As heat is added over time, the sample changes temperature and phase accordingly. Thus . heating . curve..
