Question

Nitrogen gas (N2) is contained in a flexible (balloon-like) container as shown below. Initially, the container contains 0.85 kg of N2 at a pressure of P=27.6psig, and a temperature, T1 = 128 °F. A valve is opened and releases 0.23 kg of N2. The volume is reduced to one half of the original volume, 2=1.Assume that the container 2 walls are perfectly insulated such that T = T2. Determine:(1) the initial volume, V1 in m3, (2) the final volume, 2in m3 (3) the final amount of N2 in moles, nN, and (4) the final pressure, P2, in psig. The atmospheric pressure is Patm 14.7 psia. ery the da N2 N2 =2 m3 ? mole MN = 0.85 kg 0.23 kg N2 released P 27.6 psig nN2 T,=128 °F Pz ? psig Emple ht Inces H 67 Full format solution IS required. les?

Answer 1

This problem uses the ideal gas equation and some basic calculation of moles.
