Refer to the following phase diagram (not to scale!) for nitrogen : 33.5 1.00 atm f 0.127 63.1 63.2 77.4 126.0 T Kelvin of N2 At a pressure of 1 atm, the temperature 63.2 K is called the The normal boiling point for N2 is at K The triple point pressure for N2 is atm The critical pressure for N2 is 33.5 atm. At temperatures above 126 K and pressures above 33.5 atm, N2 is a N2 is a N2 is a N2 is a at 15.4 atm and 49.4 K. e at 0.127 atm and 91.1 K. 0 at 1.00 atm and 70.0 K. (Previous Next)
