Cooling and heating curves bbc bitesize ks3

WebCooling 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.

WebHeating a system changes a substance's internal energy by increasing the kinetic energy of its particles. The temperature of the material, therefore, is related to the average kinetic energy of the molecules; The higher the temperature, the higher the kinetic energy of the molecules and vice versa. This means they move around faster WebApr 18, 2006 · How Heating and Cooling Systems Work. All climate-control devices or systems have three basic components: a source of warmed or cooled air, a means of distributing the air to the rooms being heated or cooled, and a control used to regulate the system (e.g., thermostat).
