Temperature, Thermal Energy, and Heat Lesson

​We can use thermal energy by transforming it into other forms of energy. We can also transform other forms of energy into thermal energy like in a space heater, a toaster, and an engine.

​Devices which convert electric energy into thermal energy are called heating appliances. Although all electrical appliances generate thermal energy, that is not always their intended purpose.

​A thermostat is a device that regulates the temperature of a system.

​A refrigerator is a device that uses electrical energy to transfer thermal energy from a cooler location to a warmer one.

​A heat engine is a device which converts thermal energy to mechanical energy.
