WebHeating Curves A plot of the temperature versus the amount of heat added is known as a heating curve (see Figure 10.18). These are commonly used to visually show the relationship between phase changes and enthalpy for a given substance. Figure 10.18 “Generic heating curve diagram.” WebThe boiling point of any material is the temperature at which it transitions from the liquid phase to the gas phase. This occurs at a temperature of 100 degrees centigrade for water. In fact, the Celsius scale was developed on the basis of the melting point of ice and the boiling point of liquid water and vapour.
