A sample of 22 mol o2 copm 29355 j k-1 mol-1 is originally, Ask an Expert

Academics

A sample of 2.2 mol O2 (Cop,m = 29.355 J K-1 mol-1) is originally confined in 24 dm3 at 270 K and then undergoes adiabatic expansion against a constant pressure of 600 Torr until the volume has increased by a factor of 3.0. Calculate q, w, ?U, ?T, and ?H. (The final pressure of the gas is not necessarily 600 Torr.)
