Energy transformation, also known as energy conversion, is the process of changing energy from one form to another. In physics, energy is a quantity that provides the capacity to perform work (e.g. lifting an object) or provides heat. In addition to being convertible, according to the law of conservation of energy, energy is transferable to a different location or object, but it cannot be created or destroyed.
The energy in many of its forms may be used in natural processes, or to provide some service to society such as heating, refrigeration, lighting or performing mechanical work to operate machines. For example, to heat a home, the furnace burns fuel, whose chemical potential energy is converted into thermal energy, which is then transferred to the home’s air to raise its temperature.
Examples of Energy Transformations:
1. A toaster transforms electrical energy into thermal energy.
2. A blender transforms electrical energy into mechanical energy.
3. The sun transforms nuclear energy into ultraviolet, infrared, and gamma energy all forms of electromagnetic energy.
4. Our bodies convert chemical energy from food into mechanical and electrical energy to allow us to move.
5. A natural gas stove converts chemical energy from burning into thermal energy used to cook food.
