flashpoint

Temperature of ignition

Flashpoint has both a technical and a figurative sense, connected by the idea of ignition.

In chemistry and physics, the flashpoint of a substance is the lowest temperature at which its vapors will ignite when exposed to a flame or spark.

Figuratively, a flashpoint is a place, moment, or issue where tension or conflict suddenly erupts into violence or crisis: The disputed border region has become a flashpoint between the two nations.

The word emphasizes how quickly situations can escalate from stable to volatile.
