51. The Daltons law of partial pressure can be written as
52. When two phases α and β in an alloy are in thermodynamic equilibrium, then
53. Consider an ideal solution of component A and B. The entropy of mixing per mole of an alloy containing 50 wt% B, is
54. The hydrogen content of steel in equilibrium with hydrogen gas at 1 bar pressure is 28 ppm at some temperature. Hydrogen content in the metal at the same temperature gets reduced at 1 ppm, when the equilibrium PH2 changes to . . . . . . . . bar.
55. For an ideal gas, Cp - Cv is
