A rigid vessel A, containing 0.35 m of nitrogen at 65 C and 6 bar, is connected to a rigid vessel B, that is initially evacuated (see the figure). The valve in the connecting pipe is initially closed. The valve is now opened, and nitrogen flows into B until the pressure and temperature in B become 1.5 bar and 24 C respectively. The valve is then closed and the final equilibrium pressure and temperature in A are 4 bar and 50 C respectively. The specific heat capacity, Cp, of nitrogen is 29 J mol 'K and can be treated as a constant. Calculate the total heat interaction between the nitrogen and the surrounding. Assume that the volume of the pipe and valve are negligibly small and the nitrogen can be treated as ideal gas. Gas constant is 8.3145 J mole K. Nitrogen molecular weight is 28 g/mol. A A B
