1. Physical Boot Camp 5.5B Identify the boiling and freezing/melting points of water on the Celsius scale.

2. STAAR 2013 #14; RC 1; Supporting; 471. 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?

How many more degrees Celsius must the temperature rise before it reaches the boiling temperature of water?Boiling point of water: 100ºCSo…..100 – 53 =47
