WebSep 16, 2024 · The cooling curve, a plot of temperature versus cooling time, in Figure \(\PageIndex{4}\) plots temperature versus time as a 75 g sample of steam, initially at 1 atm and 200°C, is cooled. Although we might expect the cooling curve to be the mirror image of the heating curve in Figure \(\PageIndex{3}\), the cooling curve is not an identical ... WebSuppose you have a mixture of 67% lead and 33% tin. That's the mixture from the first cooling curve plotted above. Suppose it is at a temperature of 300°C. That corresponds to a set of conditions in the area of the phase diagram labelled as molten tin and lead. Now consider what happens if you cool that mixture.
