    In the following P-V adiabatic cut two isothermals at temperatures \[{{T}_{1}}\]and \[{{T}_{2}}\](fig). The value of \[\frac{{{V}_{a}}}{{{V}_{c}}}\] will be

    A) \[\frac{{{V}_{b}}}{{{V}_{c}}}\]

    B) \[\frac{{{V}_{c}}}{{{V}_{b}}}\]

    C) \[\frac{{{V}_{d}}}{{{V}_{a}}}\]

    D) \[{{V}_{b}}{{V}_{c}}\]

    Correct Answer: A

    Solution :

    [a] We know that \[\frac{{{V}_{a}}}{{{V}_{b}}}=\frac{{{V}_{d}}}{{{V}_{c}}}\Rightarrow \frac{{{V}_{a}}}{{{V}_{d}}}=\frac{{{V}_{b}}}{{{V}_{c}}}\]
