Exothermic reactions are really interesting because they give off energy, mostly as heat.
These reactions are super important in nature. They help create energy, which keeps life and ecosystems going.
One common example of an exothermic reaction is combustion. This happens when something like wood burns. When wood burns, the chemical bonds in it break apart. Then, new bonds form with oxygen. This process releases energy that helps keep our homes warm and can even power engines.
Another key example is cellular respiration. This is how living things, including us humans, change glucose and oxygen into energy. You can think about the chemical change like this:
Glucose + Oxygen → Carbon Dioxide + Water + Energy
In this reaction, energy is released, giving us the strength to move, grow, and stay warm.
In nature, exothermic reactions also provide warmth. They are important for things like weather patterns. These reactions affect how air moves and temperatures change, which helps support life on Earth.
