Endothermic reactions are really interesting (and yes, that's a pun about temperature)!

These reactions are different from exothermic reactions. Exothermic reactions let out energy, which makes things hotter. In contrast, endothermic reactions soak up energy, usually as heat. Because of this, they can make their surroundings cooler.

Here are Some Examples of Endothermic Reactions:

• Photosynthesis: This is what plants do! They take in sunlight, carbon dioxide, and water to create glucose, or sugar.

• Dissolving ammonium nitrate in water: This is what happens in instant cold packs. When ammonium nitrate mixes with water, it absorbs heat, making things nice and cold.

Why Should You Care?

• Temperature Changes: When these reactions take in heat, the temperature around them drops. This can be really helpful, like when you use a cooling pack for a sports injury.

So, next time you think about chemistry, remember that the way energy works can change how we feel the temperature during these reactions!
