The heating and cooling curve of water
WebHeating Curves. Figure 11.4.1 shows a heating curve, a plot of temperature versus heating time, for a 75 g sample of water. The sample is initially ice at 1 atm and −23°C; as heat is added, the temperature of the ice increases linearly with time. The slope of the line depends on both the mass of the ice and the specific heat (C_s) of ice ... http://www.summitairandelectric.com/
