Here you are melting ice into water at its melting point of 0˚C. Here you are heating water up to its boiling point of 100˚C. Here you are boiling water into steam at its boiling point of 100˚C. Here you are heating steam up to whatever temperature you want. temperature Something Different is Happening in Each of the 5 Zones Each of the 5 zones shown above have their own unique formulas for calculating heats. Note that zones I, III, and V are all zones where you have only one phase present and the temperature is changing. The slopes of the curve are NOT zero in these 3 zones. As a matter of fact, the slopes of the
