Endothermic and exothermic reactions are important ideas in chemistry. They help us understand how energy changes when chemicals react.

Exothermic Reactions

• What They Are: These reactions give off energy, usually as heat.
• Example: When you mix hydrogen and oxygen, they create water.
• Think About This: Imagine a campfire. It gives off heat and light when it burns!

Endothermic Reactions

• What They Are: These reactions take in energy from their surroundings.
• Example: Photosynthesis, which is how plants make their food.
• Think About This: When you mix baking soda and vinegar, it feels cold to your skin.

Why It Matters

Learning about these reactions helps us understand how energy moves around in different processes. This knowledge is really important in areas like environmental science and making energy!
