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

3 STAAR 2013 #14; RC 1; Supporting; 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? Boiling point of water: 100ºC So…..100 – 53 = 47
