1. The problem asks about the energy transformation when gasoline is used in a car. 2. Gasoline contains chemical energy, which is converted by the engine into mechanical energy to move the car. 3. Therefore, the transformation is chemical energy \rightarrow mechanical energy. 4. For question 2, solar panels convert electromagnetic energy (sunlight) into electrical energy. 5. For question 3, when a cell phone rings, electrical energy is transformed into sound energy. 6. For question 4, burning a candle transforms chemical energy into electromagnetic energy (light) and thermal energy (heat). 7. For question 5, a wind turbine converts mechanical energy (wind) into electrical energy. 8. Question 6: Flashlight uses chemical energy converted into electrical energy, then into light. 9. Question 7: Campfire transforms chemical energy into thermal and light energy. 10. Question 8: Stove converts electrical energy into thermal energy. 11. Question 9: Lightning cloud transforms electrical energy into light, thermal, and sound energy. 12. Question 10: Sunlight (light energy) is converted into chemical energy by plants. Final answers: 1. chemical \rightarrow mechanical 2. electromagnetic \rightarrow electrical 3. electrical \rightarrow sound 4. chemical \rightarrow electromagnetic + thermal 5. mechanical \rightarrow electrical 6. chemical \rightarrow electrical \rightarrow light 7. chemical \rightarrow thermal + light 8. electrical \rightarrow thermal 9. electrical \rightarrow light + thermal + sound 10. light \rightarrow chemical
