When your friend's laptop speakers play music, the sound energy is not created from nothing. It actually comes from the electrical energy provided by the laptop's battery or power source. The electrical energy is converted into sound energy by the speakers, which vibrate and produce sound waves.
This process can be classified as a transformation of energy, rather than a transfer. This is because the electrical energy is not simply transferred from one form to another, but is actually transformed into a different form of energy (sound) through the speakers.
Your friend says their laptop speakers create sound energy when they play music. But the energy is not simply created from nothing.
Describe where the energy comes from and classify the change in energy as either a transfer or a transformation.
