Step-by-step explanation:
Turning on a flashlight: The chemical energy in the flashlight batteries is converted to electrical energy when the flashlight is turned on. The electrical energy is then converted to light (electromagnetic / radiant energy) and some thermal energy (little warmth from light in flashlight) by the light bulb. Chemical to Electrical to Light and Thermal
A Toaster: When electrical energy passes through the heating element in a toaster, it converts this electrical energy to thermal energy which helps to prepare toast. Electrical to thermal
Playing a violin: When the violin and the strings vibrate due to mechanical energy, it produces sound waves and sound energy. Mechanical to Sound
Nuclear power plant: Nuclear power plants use heat from fission to make steam that turns the turbine, creating mechanical energy. Mechanical energy turns the electric generator. Thermal to Mechanical
