What is the energy transformation that occurs when a smoke alarm goes off?

A. potential to electrical
B. sound to light
C. electrical to potential
D. electrical to sound

3 answers

The correct answer is D. electrical to sound.

When a smoke alarm goes off, it uses electrical energy to power the device, which then converts this electrical energy into sound energy to alert people to a potential fire.

are you sure this is correct

Yes, I am confident that the answer is correct. In a smoke alarm, electrical energy (from the battery or mains power) is used to operate the components of the alarm, including the circuitry that detects smoke. When smoke is detected, the alarm emits a loud sound to alert people, which is an example of electrical energy being transformed into sound energy.

So, the transformation that occurs when a smoke alarm goes off is indeed D. electrical to sound.
