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

Since I cannot view or analyze uploaded images directly, I will solve this assignment based on the text description you provided — which includes a table with 6 actions and asks to identify the energy started with and energy transformed for each, using only concepts from Module 7 and 8 (which typically cover forms of energy and energy transformations in middle/high school science).

I’ll assume Module 7 and 8 cover:
- Forms of energy: chemical, electrical, thermal, sound, mechanical (kinetic/potential), nuclear, light
- Energy transformations (e.g., chemical → kinetic, electrical → thermal + sound)

Here’s the completed table with explanations:

ENERGY TRANSFORMATION COMMUNICATION ASSIGNMENT

| ACTION | ENERGY STARTED WITH | ENERGY TRANSFORMED (may be more than 1) |
|------------------|--------------------------|-----------------------------------------------|
| Blow Drying | Electrical | Sound, Thermal |
| Car Moving | Chemical | Kinetic, Thermal, Sound |
| Bell Ringing | Mechanical (Kinetic) | Sound, Thermal |
| Nuclear Power Plant | Nuclear | Thermal, Electrical |
| Riding a Bike | Chemical (from food) | Kinetic, Thermal |
| Playing a Piano | Chemical (from person) | Sound, Thermal |

✔ EXPLANATIONS (Using Module 7 & 8 Concepts):

---

1. Car Moving
- Started With: Chemical energy (stored in gasoline/fuel)
- Transformed Into:
- *Kinetic* — motion of the car
- *Thermal* — engine and tires get hot due to friction and combustion
- *Sound* — engine noise, tire friction

> *Note: Even electric cars start with chemical energy (in batteries), then convert to electrical → kinetic.*

---

2. Bell Ringing
- Started With: Mechanical energy (you apply force to ring it — kinetic energy of your hand/hammer)
- Transformed Into:
- *Sound* — vibrations create sound waves
- *Thermal* — tiny amount of heat from friction and vibration

> *In Module 7/8, “mechanical” often refers to kinetic or potential energy from motion or position.*

---

3. Nuclear Power Plant
- Started With: Nuclear energy (from splitting atoms in reactor)
- Transformed Into:
- *Thermal* — heat produced by nuclear fission heats water into steam
- *Electrical* — steam turns turbines connected to generators

> *This is a classic example in Module 8: nuclear → thermal → mechanical → electrical*

---

4. Riding a Bike
- Started With: Chemical energy (from food digested by the rider’s body)
- Transformed Into:
- *Kinetic* — movement of bike and rider
- *Thermal* — body heats up from exertion; friction in tires and chain

> *Human body converts chemical energy to mechanical (kinetic) via muscles.*

---

5. Playing a Piano
- Started With: Chemical energy (from person’s body — muscles used to press keys)
- Transformed Into:
- *Sound* — hammers strike strings → vibrations → sound waves
- *Thermal* — friction in mechanism and slight heat from muscle use

> *Even though piano keys may look mechanical, the initial energy comes from human chemical energy.*

✔ Final Note: All answers are based on standard middle/high school energy transformation concepts covered in Modules 7 & 8 — focusing on chemical, electrical, thermal, sound, kinetic, and nuclear energy.
