What form of energy does the kettle have when water in it is boiling?
The kettle has thermal energy when the water inside it is boiling. Thermal energy is the energy associated with the motion of particles within a substance.
What is an example of thermal energy being transformed into sound energy?
An example of thermal energy being transformed into sound energy is when a heated metal object, such as a kettle on a stove, produces a whistling sound when the water inside reaches boiling point. The heat causes the metal to expand and vibrate, creating sound waves that we hear as a whistle.
What type of energy does a crank flashlight go through. mechanical or thermal?
A crank flashlight uses mechanical energy, which is converted into electrical energy to power the light.
How is sound energy and thermal energy alike?
Sound energy and thermal energy are both forms of energy that involve the movement of particles. Sound energy is the movement of energy through particles in a medium like air, while thermal energy is the internal energy of an object due to the movement of its particles. Both types of energy can be transferred from one object to another through collisions or vibrations.
What type of energy does a firecracker use?
A firecracker uses chemical energy stored in the explosive material inside it. When ignited, this chemical energy is rapidly released as heat, light, sound, and pressure, causing the firecracker to explode.
