combustion

Oxygen meets fuel

Combustion is the process of burning—a chemical reaction between a substance and oxygen that produces heat and light.

A car engine runs on internal combustion, igniting fuel in enclosed cylinders.

Spontaneous combustion occurs when materials ignite without an external spark.

Figuratively, combustion describes explosive emotional states or volatile situations.
