Which energy transformation occurs in a drum?
Answer: When you beat a drum, you give it mechanical energy by moving the drumskin back and forth (vibrating).
Which best describes the energy transformation that takes place when a log is burned in a fireplace?
Which BEST describes the energy transformation that takes place when a log is burned in a fireplace? Energy in the log is transformed into heat and light.
Which sequence of energy transformation best describes what happens on a bonfire?
Answer: In the case of burning wood, stored potential energy (in the form of chemical energy) in the log is released due to heating by other excited atoms. This chemical reaction is called combustion and requires oxygen. Combustion changes the potential chemical energy into kinetic energy in the form of heat.
Which best describes a difference between energy transformations in power plants and dams?
The difference between the energy transformations in power plants and dams would be that dams are the ones who uses mechanical energy to produce electricity. It uses turbines to convert mechanical to electrical.
What energy transformation occurs when you burn a log?
Heat energy from the logs is converted into chemical and light energy. Chemical energy from the air is converted into mechanical and light energy.
What are 5 examples of energy transfer?
- A swinging pirate ship ride at a theme park. Kinetic energy is transferred into gravitational potential energy.
- A boat being accelerated by the force of the engine. The boat pushes through the water as chemical energy is transferred into kinetic energy.
- Bringing water to the boil in an electric kettle.
What is the meaning of energy transformation?
Energy transformations are processes that convert energy from one type (e.g., kinetic, gravitational potential, chemical energy) into another. Any type of energy use must involve some sort of energy transformation.
