Heating & Cooling Curves of Water What is a Heating Curve?

WebHeating and cooling curves are graphs. They plot a substance's temperature (y-axis) against heat (x-axis). For heating curves, we start with a solid and add heat energy. For … WebCooling curve. A cooling curve of naphthalene from liquid to solid. A 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 ...
