For the following processes, calculate the indicated quantities for a system consisting of 1 mol of N 2 gas. Assume ideal gas behavior. a. The gas, initially at 10 bar, is expanded tenfold in volume against a constant external pressure of 1 bar, all at 298 K. Calculate q, w, !U and !H for the gas. b. After the expansion in part (a), the volume is fixed, and heat is added until the temperature reaches 373 K. Calculate q, w, !U and !H. c. What will be the pressure of the gas at the end of the process in part (b)? d. If the gas at 373 K is next allowed to expand against 1 bar pressure under adiabatic conditions (no heat transferred), will the final temperature be higher, remain unchanged, or be lower than 373 K? Explain your answer.
