Helium (an ideal gas under these conditions) in two well-insulated flasks is shown below with a block valve separating the flasks. The volume between the flasks is insignificant. After the valve is opened and enough time has elapsed for equilibrium to be established, fill out the Table. (Hint: Look at the enthalpy and entropy changes for the material in each flask.) (Yes. This problem is a bit "fussy.") Flask 1 Flask 2 Block valve T1 = 215°C T2 = 342°C V1=4.0 L V2=2.0 L P1=2.5 bar P2=8.1 bar R Cp=- R 6.
