What Is the Difference Between Fire and Combustion?

Fire and combustion are like best friends who work together, but they’re not exactly the same thing.

Combustion is what happens when something burns. It’s like when your favorite snack, say a marshmallow, gets hot enough to turn into gooey caramel. That’s because fire is the actual glowing, warm part you see and feel, like the flame on a birthday cake.

Imagine you're lighting a candle. The combustion happens when the wax meets the wick and starts to burn. It's like the marshmallow getting hot. But the fire is what you actually see, that flickering, bright part that warms your face.

So, fire is the visible part of burning, while combustion is the process that makes it happen. You can have one without the other. Like when you light a match, the matchstick burns (that's combustion), and the flame you see is the fire.

They're like a chef and their kitchen: the chef does the cooking (combustion) and the kitchen glows with heat (fire). Fire and combustion are like best friends who work together, but they’re not exactly the same thing.
