An ideal gas undergoes the process shown in the PV diagram below. The pressure, volume, and internal energy of the initial state (i in the diagram) are Pi = 2.0 atm, Vi = 1.7 L, and Eint i = 361.0 J, respectively. The volume and internal energy of the final state (f in the diagram) are Vf = 0.3 L, and Eint f = 1,068.3 J, respectively. The heat (in J) flowing into the gas during the process i → f is: (NOTE: 1 atm · L = 101.3 J)
