HW 2 problems Problem 20. Using the Maxwell relations, determine a relation for ( s / v ) T for a gas whose equation of state is ( P - a / v 2 ) ( v - b ) = RT . Problem 31. Using the Clapeyron-Clausius equation and the triple- point data of water, estimate the sublimation pressure of water at - 30°C and compare to the value in Table A–8. Problem 35. Derive expressions for ( a ) u , ( b ) h , and ( c ) s for a gas whose equation of state is P ( v - a ) = RT for an isothermal process. Problem 37. Derive an expression for the specific-heat difference c p - c v for ( a ) an ideal gas, ( b ) a van der Waals gas, and ( c ) an incompressible substance Problem 53. Steam is throttled slightly from 1 MPa and 300°C. Will the temperature of the steam increase, decrease, or remain the same during this process? Problem 59. What is the error involved in the ( a ) enthalpy and ( b ) internal energy of CO 2 at 350 K and 10 MPa if it is assumed to be an ideal gas? Problem 69.
