Identify the energy transformations that take place in a battery-powered flashlight:(3 points)
1. Chemical energy to electrical energy: In a battery-powered flashlight, the chemical energy stored in the batteries is converted into electrical energy. This conversion occurs through chemical reactions within the battery.
2. Electrical energy to light energy: The electrical energy produced by the batteries is then converted into light energy. This occurs when the electrical current flows through the bulb or LED (light-emitting diode) of the flashlight, causing it to emit light.
3. Some energy is also converted into heat energy: During the process of converting chemical energy to electrical energy and then to light energy, a small amount of energy is typically lost as heat energy. This heat energy is generated due to the resistance in the electrical circuit of the flashlight and is dissipated into the surrounding environment.
