: My roommate were talking about at what elevation
: you would have to be at for water to boil at room temp. (75 deg f for us)
: I figured out that P1/P2=T1/T2 and came up with 0.796 atmos.
: But I dont know how to get that to an elevation above sea level.
: Any one no the answer and can you explan a little.

It does not work like that. In order for it to boil the
atmospheric pressure has to be equal or larger
than the vapor pressure for water @ 75 deg F which
is approximately 0.5 pounds per square inch. So,
you will need to go to an elevation where the
pressure is 0.5/14.7 = 0.034 atmos. !!(space shuttle altitude?)
Hope this helps,
