What are exothermic reactions?

An exothermic reaction is when energy is released as heat, like a cozy fire warming your hands.

Imagine you have a pile of kindling and matches. When you light the match, it starts burning, and soon the kindling catches fire too. The flames give off warmth, that’s because the reaction between the match and oxygen in the air makes heat. This is just like what happens in an exothermic reaction, where energy comes out as heat.

Think of it like making hot chocolate. When you add hot water to cocoa powder, it warms up your mug, the mix gets hotter because energy is being released. That’s similar to how some chemical reactions work: they give off heat, just like that hot drink.

Sometimes, you can feel this in real life too, like when you light a candle or even when you open a soda bottle and it fizzes up quickly. These are all examples of exothermic reactions, where things get warmer because energy is let out as heat.
