WebCooling Curves. 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 … WebA cooling curve is a line graph that represents the change of phase of matter, typically from a gas to a solid or a liquid to a solid. The independent variable (X-axis) is time and the dependent variable (Y-axis) is temperature. [1] Below is an example of a cooling curve used in castings .
