Question

Describe the energy transformations in each:1. When the flashlight is turned on, a flow of electrons is created by the batteries. The electricity passes through the incandescent lightbulb, causing the tungsten filament in the lightbulb to heat up. When the metal is hot enough, photons of light are emitted.

Answer 1

First, it is the chemical energy because of the batteries, then this energy is transforming to electrical because of the flowing of electrons. Before this, the electrical energy is going to be light energy for the light bulb and finally, we have the heat energy of the light bulb. The order is:

$\text{Chemical}\to electricity\to light\to heat.$
