relationship between temperature and pressure, what temperature would boiling water attaining the open pot of a backpacker camping at 10000 feet above sea level where the air pressure is about one third of the pressure at sea level? relationship between temperature and pressure, what temperature would boiling water attaining the open pot of a backpacker camping at 10000 feet above sea level where the air pressure is about one third of the pressure at sea level? relationship between temperature and pressure, what temperature would boiling water attaining the open pot of a backpacker camping at 10000 feet above sea level where the air pressure is about one third of the pressure at sea level?

Explanation / Answer

As the altitude increases, there will be a pressure drop that results in the boiling of water at lower temperatures in backpacking stoves. There will be a 1/2 pound drop in pressure for every 1000 feet increase in altitude. Hence, if the pressure at sea level is 14.7 psi, it is only 10.2 psi at 10,000 feet altitude above the sea level. At sea level, water boils at a temperature of 100 0C,(212 0F) and at 10,000 feet altitude above the sea level, it boils at only 90 0C (194 0F). In conclusion, there is a direct proportionality between pressure and temperature. As altitude increases, the pressure drops and this pressure drop results in a drop in temperature of the boiling point.
