Figure shows P versus V graph for various processes performed by an ideal gas. All the processes are polytropic following the process equation `PV^(k) =` constant.
(i) Find the value of k for which the molar specific heat of the gas for the process is `(C_(P)+C_(V))/(2)`. Does any of the graph given in figure represent this process?
(ii) Find the value of k for which the molar specific heat of the gas is `C_(V) + C_(P)`. Assume that gas is mono atomic. Draw approximately the P versus V graph for this process in the graph given above.
