  Consider the reversible processes for 1.0 mol of an ideal gas as shown in the figure. Processes 2 and 4 are adiabatic. \(w_1,w_2,w_3\) and \(w_4\) represent work done (in calories) in processes 1, 2, 3 and 4, respectively. \(\Delta U_2\) and \(\Delta U_4\) are changes in internal energy for processes 2 and 4, respectively. [Use \(R = 2\ \text{cal}\ \text{K}^{-1}\text{mol}^{-1}\)]
  

  

  • \(w_1+w_2+w_3+w_4=0\)
  • \(w_1+w_3=-2T_1\ln\left(\frac{V_2}{V_1}\right)-2T_2\ln\left(\frac{V_4}{V_3}\right)\)
  • \(w_2+w_4=\Delta U_2-\Delta U_4\)
  • \(w_1+w_2=2T_1\ln\left(\frac{V_2}{V_1}\right)\)
