Multiple Select

Chemical energy is stored inside substances and can change into other forms of energy. Which of the following are examples of chemical energy being used?

• Burning wood to produce heat

• Eating food to move and grow

• Hammering a nail into wood

• Lightning striking during a storm

Multiple Choice

Compare and contrast chemical energy and electrical energy. How are they similar and how are they different?

• Chemical energy is used in batteries, while electrical energy is found in food sources.
• Chemical energy is produced by solar panels, whereas electrical energy is derived from fossil fuels.
• Chemical energy is a form of kinetic energy, while electrical energy is static in nature.
• Chemical energy is stored in chemical bonds, while electrical energy is the energy of moving charges. They can be converted into each other but differ in their sources and applications.
