Combustion
Combustion explained in an easy to understand way:
Imagine trying to stay warm on a cold winter's night by wrapping yourself in a blanket. Just like how the blanket acts as a barrier, trapping your body heat and radiating warmth, combustion is the process where a fuel reacts with oxygen to generate heat and light. In this analogy, the fuel is akin to your body, oxygen is like the air surrounding you, and the heat and light produced are similar to the warmth you feel under the blanket, as both situations involve a release of energy to create warmth and comfort.
Practice Version
Combustion: The burning of a fuel, where it reacts with oxygen to create heat and light, is called combustion. Combustion is when something burns and releases energy in the form of heat and light.
