Answer» curve AB represents isothermal PROCESS and BC adiabatic process Differentiating w.r.t. V , we GET `(dP)/(dV) V^(gamma) + PgammaV^(gamma-1) = 0" or " (dP)/(dV) = - (gammaP)/V` For isothermal process, PV = constant Hence, `(dP)/(dV) = - P/V` Now dP/dV is the slope of the(P - V) GRAPH. Thus, the slope of the (P-V ) graph for an adiabatic process is `gamma`times that for an isothermal process. Hence, curves BC and DA both represent adiabatic process and curves AB and CD both represent isothermal process. |
