  1. Air at an initial state of , , and  is compressed slowly in an isothermal process to , , and . The air can be treated as ideal gas. What is the boundary work ?_________

     

      A.

     

      B.

     

      C.

     

      D.

     

Air at an initial state of \( T_1, P_1, \) and \( V_1 \) is compressed slowly in an isothermal process to \( T_2, P_2, \) and \( V_2 \). The air can be treated as an ideal gas. What is the boundary work \( W_b \)?

A. \[ P_1 V_1 \ln \left( \frac{P_2}{P_1} \right) \]

B. \[ P_2 V_2 \ln \left( \frac{P_2}{P_1} \right) \]

C. \[ \frac{(P_1 + P_2)(V_2 - V_1)}{2} \]

D. \[ P_2 V_2 \ln \left( \frac{V_2}{V_1} \right) \]
