Here are some everyday examples of how chemical energy changes into other types of energy:

1. Cars and Engines:

   • In cars, the gasoline acts like stored energy. When it burns in the engine, it changes about 25% of that energy into movement energy, which helps the car drive.

2. Breathing for Energy:

   • In our bodies, when we eat sugar (a type of chemical energy), we use a process called cellular respiration. This process turns about 40% of the energy in sugar into ATP. ATP is like fuel for our cells, giving them the energy they need to work.

3. Batteries:

   • Batteries, like the ones in our phones or laptops, store chemical energy. When we use the battery, that chemical energy changes into electrical energy. For example, lithium-ion batteries can hold about 250 watt-hours of energy for every kilogram, making them great for powering our devices.

4. Energy from Food:

   • When we eat, our body takes the nutrients (which are chemical energy) and turns them into kinetic energy when we move around. Our bodies can use about 25% of the energy in food for our activities.

These examples show how chemical energy is an important part of our daily lives and how it changes into energy we can use!
