Your answerSelect all correct options. You can choose more than one.

For single-phase equilibrium at a given temperature, chemical potentials of the components change with alloy composition.

For two-phase equilibrium at a given temperature, chemical potential of any component in both phases is the same.

For two-phase equilibrium at a given temperature, chemical potentials of the components change with alloy composition.

For single-phase equilibrium at a given composition, chemical potentials of the components do not change with temperature.
