Apologies, but I am unable to visualize and interpret visual content or tables as I am a text-based AI model. However, I can help answer your question if you provide me with the options available in the table.
The energy transformation that occurs when a smoke alarm goes off is electrical to sound.
The correct answer is "electrical to sound." When a smoke alarm goes off, there is a transformation of energy from electrical energy to sound energy.
To understand how to arrive at this answer, we need to understand the components and working principles of a smoke alarm. A smoke alarm typically consists of a sensing device (like a photoelectric or ionization chamber), a power source (such as a battery or electrical outlet), and an audio device (a buzzer or speaker).
1. First, electrical energy is required to power the smoke alarm. This electrical energy can come from a battery or an electrical outlet.
2. The sensing device in the smoke alarm is designed to detect the presence of smoke particles in the air. When smoke enters the chamber, it triggers a response from the sensing device.
3. Once the sensing device detects smoke, it sends an electrical signal to the audio device (buzzer or speaker).
4. The electrical signal is converted into sound energy by the audio device, producing a loud sound or alarm to alert people of potential danger.
Therefore, the energy transformation that occurs when a smoke alarm goes off is from electrical energy to sound energy.
