Boiling

Boiling is the rapid thermal process where liquid transforms into gas by absorbing enough Energy to break molecular bonds. It occurs when a liquid reaches its Boiling point, a Constant that varies by substance and atmospheric pressure. Water boils at 100°C at sea level, but lower on mountains where pressure drops.

This ancient technique powers Kitchen chemistry—from cooking herbs to sterilizing water for safety. Boiling is distinct from Evaporation, which happens slowly at any Temperature; boiling is violent and visible. The bubbles aren't air, but vapor escaping from the liquid's interior.

Beyond cooking, boiling appears everywhere: industrial processes use it for distillation and chemical synthesis; planetary scientists study boiling on Venus and other planets; Engineering harnesses boiling in power plants and precision cooking methods.

Understanding boiling requires grasping phase transitions—moments where matter's identity shifts fundamentally. It's both utterly mundane and genuinely wondrous: a kettle's whistle contains the same physics as stellar atmospheres.
