Find how altitude lowers the boiling point of water.
Air pressure falls with altitude, so water boils at a lower temperature, about one degree cooler per three hundred meters. At altitude, food cooks slower because the water is cooler, which matters for pasta, eggs and canning schedules.
Boiling Point at Altitude
Boiling point C = 100 - altitude(m) / 300
Boiling point C = 100 - altitude(m) / 300 Air pressure falls with altitude, so water boils at a lower temperature, about one degree cooler per three hundred meters.
