How Do Geysers Work? http://www.eepybird.com/exp214.html Water goes somewhere And pressure is released Entire column Near boiling, but mostly hotter than 100°C Filling and Heating Expanding steam Empty pipe Boiling releases Pressure & boiling point decreases. Boiling runs away Water under Pressure has Higher boiling Point: Pressure cooker steam Superheated water begins to boil Filling and Heating
