find the work done by the system in reversible process for which PV^n=constant?
Work done is the integral form for dw in reversible process that is:dW = Pext. dVNow we have given as: => PV^n = korP = kV^-nPut Pressure into dw eqn. we get,dW = k(V^-n)dVIntegerating both sides we get,W = k(V^(-n+1)/(1 – n))again put value of k this time we get,W = PV^n(V^(-n+1)/(1 – n)) = > PV/(1 – x) => nRT/(1 – n)
