  • question_answer
    A thermodynamic system undergoes cyclic process ABCDA as shown in figure. The work done by the system is

    A)             \[{{P}_{0}}{{V}_{0}}\]

    B)             \[2{{P}_{0}}{{V}_{0}}\]

    C)             \[\frac{{{P}_{0}}{{V}_{0}}}{2}\]

    D)            Zero

    Correct Answer: D

    Solution :

                       WBCOB = ? Area of triangle BCO \[=-\frac{{{P}_{0}}{{V}_{0}}}{2}\] WAODA = + Area of triangle AOD \[=+\frac{{{P}_{0}}{{V}_{0}}}{2}\]
