Through the introduction of the molar gravitational potential energy for component B,we derive the fundamental thermodynamic equations for a multi-component system in a gravitational field.The gravitational chemical potential is defined,allowing for the determination of the direction and extent of changes.Concluding,we provide application examples of the criteria based on the gravitational chemical potential:the pressure distribution formula for an ideal gas as a function of altitude,and the sedimentation equilibrium formula for sol particles in a medium.
