SUMMARY
The discussion centers on the implications of a constant number of particles on the chemical potential (μ) and Helmholtz free energy (F) in thermodynamics. When F does not depend on the number of particles, it indicates that the chemical potential μ approaches zero. The correct definition of chemical potential is clarified as μ = F + PV, and the relationship between Helmholtz free energy and the number of particles is established through the equation dF = -SdT - PdV + μdN.
