The atmospheric pressure falls at half its value for approximately 5.6 km = 18 400 ft. This means that the atmospheric pressure at 7000 ft is:

p = 30.00 in Hg / 2^(7000/18400) = 23.05 in Hg

At this presure the boiling point of water is about 92.5 degrees Celsius (or 198.5 degrees Fahrenheit).

30"Hg is more or less atmospheric.
BP of water = 100Â°C (212Â°F)
