In a heating curve, the substance is heated usually when it is in the solid phase until it becomes a gas at the end. Heating involves addition of heat energy. 2020-12-25 · Draw a heating cooling curve for a substance that freezes at -57° C and boils at 125.6°. Label each phase of the curve with its appropriate name.

And this The length of the line of the heating curve for water at 100 °C is the amount of heat required to change all of the liquid into a gas. This heat is called the change in enthalpy of vaporization, Δ H vap. Vaporization is a specific scientific term for changing a pure liquid into the gas phase. Cooling Curves Heating curves show how the temperature changes as a substance is heated up. Cooling curves are the opposite. They show how the temperature changes as a substance is cooled down. Just like heating curves, cooling curves have horizontal flat parts where the state changes from gas to liquid, or from liquid to solid.
