Illustration with help of example energy transformation?

An example of energy transformation is when a person turns on a flashlight. The chemical energy stored in the batteries is converted into electrical energy, which then powers the light bulb to produce light energy. This light energy is then transformed into heat energy as the bulb emits heat while producing light.

Energy Transformation Illustration

Example: Electrical Energy to Heat Energy

Input Energy: Electrical energy from a toaster

Output Energy: Heat energy from the toasted bread

Steps of Energy Transformation:

1. Electrical Energy to Resistance Heating: When electrical current flows through the heating element of the toaster, it encounters resistance. This resistance causes heat to be generated.
2. Heat Energy to Bread: The heat generated from the heating element radiates outwards and transfers to the bread surface.
3. Heat Energy to Inner Bread: The heat from the surface gradually penetrates into the inner bread through conduction.
4. Heat Energy to Browning and Toasting: The heat causes the bread's surface to brown and the interior to toast.

Additional Notes:

- In this example, some of the electrical energy is also transformed into sound energy (the sound of the toaster) and light energy (the glow of the heating element).
- Energy transformations are rarely 100% efficient. In this case, some of the electrical energy is lost as heat due to the resistance of the wires and other components.
