Answer:
16. Examples of matter containing chemical energy include: Coal: Combustion reaction converts chemical energy into light and heat. Wood: Combustion reaction converts chemical energy into light and heat. Petroleum: Can be burned to release light and heat or changed into another form of chemical energy, such as gasoline
17. an electric motor converts electrical energy into mechanical energy. A generator converts mechanical energy into electrical energy. A hydroelectric powerplant converts the mechanical energy of water in a storage dam into electrical energy.
wind energy
In a hydroelectric plant, falling water is used to spin the turbine blades. The blades turn the generator to create electrical energy. In a windmill, wind power turns the turbine blade, which – you've guessed it! – makes the generator create electrical energy.
18. Here, the example of electrical energy converted into the sound energy are Microphone. As we know that energy is present in the many forms around us such as kinetic energy, potential energy, electrical energy, sound energy, thermal energy and others form of energies.
19. An electric motor converts electrical energy into mechanical energy. A generator converts mechanical energy into electrical energy. A hydroelectric powerplant converts the mechanical energy of water in a storage dam into electrical energy. ... A steam engine converts the heat energy of steam into mechanical energy.
20. Coal: The combustion reaction converts chemical energy into light and heat. Wood: Combustion converts chemical energy into light and heat. Petroleum: Petroleum may be burned to release light and heat or changed into another form of chemical energy, such as gasoline.
Explosives - as explosives go off, chemical energy stored in the explosive is transferred into sound energy, kinetic energy, and thermal energy. Storage batteries - They contain chemical energy which is converted into electrical energy.
