Absolutely! Let’s solve this “Energy Transfers” worksheet step by step. The goal is to identify the
type of energy going IN to each device, the
device itself, and the
type of energy coming OUT.
We are given these energy types to choose from:
> Chemical, Kinetic, Electrical, Light, Thermal, Sound, Solar
---
✔ EXAMPLE (Given for reference):
-
Device: Battery powered torch
-
Energy in: Chemical potential (from the battery)
-
Energy out: Light Energy (the torch emits light)
This makes sense — chemical energy stored in the battery is converted into electrical energy, which powers the bulb to produce light.

## 🔥 1. Kettle
What does a kettle do?
→ It heats water. Most kettles are electric (plugged in), so they use electricity to generate heat.
Energy in:
Electrical
*(Electricity flows into the kettle’s heating element)*
Energy out:
Thermal
*(The heating element gets hot, transferring thermal energy to the water)*
> 💡 Sometimes kettles also make a sound when boiling — but the *main* output energy type here is
thermal. If the question allowed multiple outputs, you could add “Sound”, but since there’s only one box, go with the primary function: heating →
Thermal.
✔ Answer for Kettle:
- Energy in:
Electrical
- Energy out:
Thermal

## 🎤 2. Microphone
What does a microphone do?
→ It captures sound waves (vibrations in air) and converts them into an electrical signal.
So:
Energy in:
Sound
*(Your voice or music creates sound waves that hit the mic)*
Energy out:
Electrical
*(The mic converts those vibrations into an electrical current that can be amplified or recorded)*
✔ Answer for Microphone:
- Energy in:
Sound
- Energy out:
Electrical

## 🍳 3. Gas Oven
What does a gas oven do?
→ It burns natural gas (or propane) to produce heat for cooking.
So:
Energy in:
Chemical
*(Gas contains stored chemical potential energy — released when burned)*
Energy out:
Thermal
*(The flame produces heat — thermal energy — to cook food)*
> ⚠️ Note: Some ovens might also emit light (glowing burner) or sound (gas hiss), but again, the main purpose is heating →
Thermal is correct.
✔ Answer for Gas Oven:
- Energy in:
Chemical
- Energy out:
Thermal

## 📝 Final Answers Summary:
| Device | Energy in | Energy out |
|---------------|---------------|--------------|
| Kettle | Electrical | Thermal |
| Microphone | Sound | Electrical |
| Gas Oven | Chemical | Thermal |
