Answer this plz Share with your friends Share 0 Anshu Agrawal answered this Dear student, Isothermal bulk modulus is ratio of volumetric stress to volumetric strain at constant temperature i.e., B=−dp/(dV/V)=−V(dP/dV) T Differentiate the ideal gas equation, PV=nRT at constant T to get V(dP/dV) T =−P/V substitute dP/dV from second equation into first equation to get B=P. Hence, option (B) is correct answer. Regards 0 View Full Answer
