# fire (combustion)

a process where matter transforms energy into heat and light

- Computed level: L21 (depth in the emergence graph, not abstraction)

## Emergence
**Emerges from:** [matter](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-matter.substance), [energy](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-energy.capacity), [change](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-change.process), [heat](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-heat.thermal), [light](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-light.visual)

**Through:** matter and energy interact through change, emitting heat and light as byproducts of transformation.

**Novel properties:**
- emission of thermal energy
- emission of visible light
- sustained exothermic reaction

## Examples
- The 2020 Gospers Mountain fire in Australia burned 500,000 hectares over 74 days, releasing stored chemical energy from eucalyptus biomass. *(ecology)*
- A Bunsen burner in a Paris laboratory on June 5, 1857, ignited methane from the city gas line, producing a blue flame at 1,200°C. *(engineering)*
- Lightning struck a dry redwood in California’s Sequoia National Park on August 16, 2021, igniting the KNP Complex fire. *(meteorology)*
