Describe the difference between energy transfer and energy transformation. Include an example of each process.

Energy transfer and energy transformation are two fundamental concepts in physics, and they describe different processes involving energy.

Energy Transfer: Energy transfer refers to the movement of energy from one place or object to another without changing its form. This process involves the relocation of energy from one system to another.

Example: When you heat a pot of water on a stove, thermal energy is transferred from the stove to the pot and then to the water. The energy remains in the form of heat throughout the process.

Energy Transformation: Energy transformation, on the other hand, involves the change of energy from one form to another. This process is also known as energy conversion.

Example: In a light bulb, electrical energy is transformed into light energy and thermal energy. The electrical energy supplied to the bulb is converted into light, which illuminates the room, and heat, which warms the bulb.

In summary, energy transfer involves the movement of energy in the same form from one place to another, while energy transformation involves changing energy from one form to another.
