Temperature (C). Time (s). Crossing the Line…. 100.0 g of liquid water is heated from 1.0˚C to 111˚C. How much energy was added to the water to cause this temperature change? C ice = 2.1 J/g˚C H fusion = 334 J/g C water =4.2 J/g˚C H vap = 2260 J/g C steam = 31.3J/g˚C.

Temperature (C) Time (s)
Crossing the Line… 100.0 g of liquid water is heated from 1.0˚C to 111˚C. How much energy was added to the water to cause this temperature change? Cice = 2.1 J/g˚C Hfusion = 334 J/g Cwater =4.2 J/g˚C Hvap = 2260 J/g Csteam = 31.3J/g˚C
Crossing the Line Again… 100.0 g of solid water is heated from -10.0˚C to some new temp. If 73.1 kJ of heat are added to the ice, what is the final temperature of the resulting material? Cice = 2.1 J/g˚C Hfusion = 334 J/g Cwater =4.2 J/g˚C Hvap = 2260 J/g Csteam = 31.3J/g˚C
Crossing the Line One Last Time… 100.0 g of water at 70.0˚C is heated with a burner. If 171 kJ of heat are added to the water, what percentage of the water turns to steam? Cice = 2.1 J/g˚C Hfusion = 334 J/g Cwater =4.2 J/g˚C Hvap = 2260 J/g Csteam = 31.3J/g˚C
