Question

use energy words like:

• electrical energy
• light energy
• heat (thermal) energy
• sound energy
• mechanical (motion) energy

household items

household item energy transformation

1 light bulb
2 television
3 toaster
4 fan
5 doorbell
6 microwave
7 blender
8 washing machine
9 lamp
10 alarm clock

Explanation:

Each household item converts electrical energy (the input from a power source) into the listed output energy forms, with some items producing multiple energy types as byproducts or primary functions.

Answer:

1. Light bulb: Electrical energy → Light energy + Heat (thermal) energy
2. Television: Electrical energy → Light energy + Sound energy + Heat (thermal) energy
3. Toaster: Electrical energy → Heat (thermal) energy
4. Fan: Electrical energy → Mechanical (motion) energy + Heat (thermal) energy
5. Doorbell: Electrical energy → Sound energy
6. Microwave: Electrical energy → Heat (thermal) energy
7. Blender: Electrical energy → Mechanical (motion) energy + Sound energy + Heat (thermal) energy
8. Washing machine: Electrical energy → Mechanical (motion) energy + Heat (thermal) energy
9. Lamp: Electrical energy → Light energy + Heat (thermal) energy
10. Alarm clock: Electrical energy → Sound energy + Light energy (for display) + Mechanical (motion) energy (for analog clocks)
