1 . True/False (10 points each). Classify the statements below as either True or False (No explanation required). A. At P = 1 atm and T = 298K the chemical potential of liquid water is lower than that of the H 2 O gas. True B. When two different phases coexist, their molar entropies are the same. False C. The entropy of any material as a function of the volume and temperature is described by the expression: l nl n V S CT R V =+ False D. When the temperature of any material is increased from T 1 to T 2 while maintaining its pressure constant, the change of its entropy is given by the expression: 2 1 / T P T S C dT T ∆= True E. The molar enthalpy H of any material is equal to its formation enthalpy, f H False F. The coexistence curve between liquid and solid phases is described by the Clapeyron-Clausius equation: 2 liquid solid HH dP P dT RT = False G. The chemical potential of an incompressible liquid changes with pressure according to the equation: 0 0 (,) l n (/ ) PT P T RT P P µµ False H.
