WebJust like heating curves, cooling curves have horizontal flat parts where the state changes from gas to liquid, or from liquid to solid. You are likely to have used salol or stearic acid in a school practical lesson to make your own cooling curve. Salol has a melting point of about 45°C and stearic acid has a melting point of about 69°C. 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 cooling curves, we start with the gas phase and remove heat energy. Cooling and heating curves have five segments. Let's study each one by looking at heating ice to steam.
