During a process , p & V to be related by the equation - $\;p=\large\frac{p_{0}}{1+(\large\frac{V_{0}}{V})^2}\;$ , $\;p_{0}\;$ & $\;V_{0}\;$ are constants . Change in temperature of the gas . When volume is changed from $\;V=V_{0}\;$ to $\;V=5V_{0}$

Question

$(a)\;\large\frac{6}{13}\;\large\frac{p_{0}V_{0}}{nR}\qquad(b)\;-\large\frac{6}{13}\;\large\frac{p_{0}V_{0}}{nR}\qquad(c)\;\large\frac{1}{13}\;\large\frac{p_{0}V_{0}}{nR}\qquad(d)\;-\large\frac{1}{13}\;\large\frac{p_{0}V_{0}}{nR}$
