Solved ENERGY TRANSFORMATION COMMUNICATION ASSIGNMENT | Chegg.com - Free Printable

Let’s go through each action one by one and think about what energy it starts with, and what energies it turns into.

---

1. Car Moving

- A car that moves usually runs on gasoline (or diesel). That fuel has chemical energy stored in it.
- When the engine burns the fuel, it makes the car move → that’s kinetic energy (energy of motion).
- Also, cars get hot when they run → that’s thermal energy.
- And you can hear the engine and tires → that’s sound energy.

✔ So:
Energy started with: Chemical
Energy transformed to: Kinetic, Thermal, Sound

2. Bell Ringing

- To ring a bell, someone usually pulls a rope or hits it — that means they’re using their muscles → which comes from chemical energy in their body (from food).
- The bell moves back and forth → that’s kinetic energy.
- The bell makes noise → that’s sound energy.
- There might be a tiny bit of heat from friction, but we’ll stick to main ones.

✔ So:
Energy started with: Chemical
Energy transformed to: Kinetic, Sound

*(Note: If it’s an electric bell, it would start with electrical — but since no plug or battery is shown, and it looks like a hand-held bell, chemical from human muscle is correct.)*

3. Nuclear Power Plant

- This plant uses uranium or other nuclear fuel → that’s nuclear energy.
- It heats water to make steam → that’s thermal energy.
- Steam spins turbines → that’s kinetic energy.
- Turbines spin generators → that makes electrical energy.
- Also, there’s always some sound and waste heat → sound and thermal.

But let’s keep it simple and focus on the main transformation chain:

Nuclear → Thermal → Kinetic → Electrical

So for this table, we list what it STARTS with and what it TRANSFORMS INTO overall.

✔ So:
Energy started with: Nuclear
Energy transformed to: Thermal, Kinetic, Electrical *(and maybe sound/heat as extras, but these are the big three)*

4. Riding a Bike

- You pedal using your legs → powered by chemical energy from food.
- The bike moves → kinetic energy.
- Your body gets warm → thermal energy.
- Chain and wheels make noise → sound energy.

✔ So:
Energy started with: Chemical
Energy transformed to: Kinetic, Thermal, Sound

---

5. Playing a Piano

- You press keys with your fingers → again, chemical energy from your body.
- Inside the piano, hammers hit strings → that’s kinetic energy.
- Strings vibrate and make music → sound energy.
- Maybe a little heat from friction, but not major.

✔ So:
Energy started with: Chemical
Energy transformed to: Kinetic, Sound

Now let’s put all answers together neatly.
