Finding endothermic reactions in our daily lives can be interesting and useful!
An endothermic reaction is one that takes in energy, usually from the surroundings. This often makes things cooler. Here are some examples you might notice:
Photosynthesis: This is a natural process that happens in plants. They take in sunlight to turn carbon dioxide and water into glucose and oxygen. The sunlight is very important for this process.
Dissolving Salts: When you mix certain salts, like ammonium nitrate, with water, the water gets colder. This happens because the reaction is endothermic. The salt absorbs energy to break apart into smaller parts.
Baking Soda and Vinegar: When you mix baking soda with vinegar, it creates a fizzing reaction. This reaction absorbs heat, making the area around it feel cooler. It’s another endothermic process!
Cold Packs: Many cold packs that you use for injuries contain chemicals like ammonium nitrate or urea. When you activate them, these chemicals go through an endothermic reaction that takes in heat and makes the pack feel cold.
By noticing these reactions, you can learn more about how energy changes work in chemistry!
