Question:
For an ideal gas, AB and CD are two isothermals at temperatures T1 and T2(\(T_1\gt T_2\)), respectively. AD and BC represent two adiabatic paths as shown in figure. Let VA, VB, VC and VD be the volumes of the gas at A, B, C and D respectively. If \(\frac{V_c}{V_B}=2\), then \(\frac{V_D}{V_A}=\)______.
