Cooling curves

Cooling curves are graphical representations that show how the temperature of a substance changes as it cools over time. When a material, such as metal or liquid, is heated and then allowed to cool, the curve illustrates this temperature decline, highlighting key phases like solidification or changes in state (e.g., from liquid to solid). The curve typically flattens during phase transitions, indicating that energy is released while the temperature remains constant. Cooling curves help scientists and engineers understand materials' properties and behaviors, making them essential in fields like metallurgy, chemistry, and materials science.
