# hot (temperature)

a state where a matter has more energy capacity than usual for that kind of matter

- Computed level: L19 (depth in the emergence graph, not abstraction)
- Status: review  ·  Domain: everyday  ·  Arena: hot

## Emergence
**Emerges from:** [energy](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-energy.capacity), [state](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-state.condition), [matter](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-matter.substance), [capacity](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-capacity.size), [pattern](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-pattern.regularity), [potential](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-potential.capacity), [usual](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-usual.common)

**Through:** The capacity.size and potential.capacity modulate energy.capacity within matter.substance, conditioned on state.condition and what is usual.common, producing a deviation marked by heightened energy load.

**Novel properties:**
- elevated energy load
- deviation from typical capacity
- persistent energetic state

## Examples
- The Sun's core reaches 15 million °C, sustaining fusion against radiative cooling. *(physics)*
- Death Valley hit 56.7°C in 1913, the highest reliably recorded air temperature on Earth. *(geography)*
- The Fukushima reactor cores exceeded 2000°C during meltdown after cooling failed. *(engineering)*
