Step-by-step solution for: Energy Conversion worksheet
Let's go through each image and determine the input and output energy forms, following the instruction to include the word "Energy" in each answer (e.g., Chemical Energy → Electrical Energy).
---
- Input: Chemical Energy (from food)
- Output: Kinetic Energy
- ✔ Chemical Energy → Kinetic Energy
> *Explanation:* The person uses stored chemical energy from food to move their body, producing motion (kinetic energy).
---
- Input: Chemical Energy (in the match head)
- Output: Heat Energy + Light Energy
- ✔ Chemical Energy → Heat Energy + Light Energy
> *Explanation:* When a match burns, the chemical energy stored in the match is released as heat and light.
---
- Input: Light Energy (from the sun)
- Output: Chemical Energy (stored in the plant via photosynthesis)
- ✔ Light Energy → Chemical Energy
> *Explanation:* Plants use sunlight to convert carbon dioxide and water into glucose (chemical energy) through photosynthesis.
---
- Input: Electrical Energy
- Output: Kinetic Energy (blades spinning) + Sound Energy
- ✔ Electrical Energy → Kinetic Energy + Sound Energy
> *Explanation:* The blender converts electrical energy into motion (kinetic energy) of the blades and produces sound.
---
- Input: Chemical Energy (in fireworks)
- Output: Light Energy + Sound Energy + Heat Energy
- ✔ Chemical Energy → Light Energy + Sound Energy + Heat Energy
> *Explanation:* Fireworks contain chemicals that release energy as bright lights, loud sounds, and heat when ignited.
---
- Input: Chemical Energy (from batteries)
- Output: Electrical Energy → Light Energy
- ✔ Chemical Energy → Electrical Energy → Light Energy
> *Explanation:* Batteries store chemical energy, which is converted to electrical energy, then to light energy in the bulb.
---
- Input: Electrical Energy
- Output: Heat Energy (to toast bread)
- ✔ Electrical Energy → Heat Energy
> *Explanation:* The toaster uses electricity to generate heat, which toasts the bread.
---
- Input: Chemical Energy (in wax)
- Output: Light Energy + Heat Energy
- ✔ Chemical Energy → Light Energy + Heat Energy
> *Explanation:* As the candle burns, the wax undergoes combustion, releasing light and heat.
---
1. Chemical Energy → Kinetic Energy
2. Chemical Energy → Heat Energy + Light Energy
3. Light Energy → Chemical Energy
4. Electrical Energy → Kinetic Energy + Sound Energy
5. Chemical Energy → Light Energy + Sound Energy + Heat Energy
6. Chemical Energy → Electrical Energy → Light Energy
7. Electrical Energy → Heat Energy
8. Chemical Energy → Light Energy + Heat Energy
