WebNov 26, 2024 · 12.5: Interpretation of Cooling Curves. The melting temperature of any pure material (a one-component system) at constant pressure is a single unique temperature. The liquid and solid phases exist together in equilibrium only at this temperature. When cooled, the temperature of the molten material will steadily decrease … WebHeating and cooling graphs are used to summarise: How the temperature of a substance changes when energy is transferred to or away from it. Where changes of state occur. …

WebCooling curve. A cooling curve is actually a line graph representing the change in the state of matter of a substance, either from solid to liquid or liquid to solid. In this graph, time is usually represented on the x – axis and temperature on the y – axis. The particles in the wax in the solid state slowly start to get more energy when ...
