Exothermic Reaction

Real World Example

Imagine you're sitting in a crowded room, and it starts to feel uncomfortably warm because everyone is radiating body heat. This situation is similar to an exothermic reaction where energy is released into the surroundings, just like how the people in the room release heat. In both cases, the source (whether it's people or a chemical reaction) emits energy into the environment, causing the surrounding area to warm up, just as burning wood releases heat into a room.
