Essential Laboratory Skills Guide

Consider two systems; S₁ and S₂ at the same temperature and capable of exchanging particles. If there is a change in the potential energy of a system; for example μ₁>μ₂ (μ is Chemical potential) an energy flow will occur from S₁ to S₂, because nature always prefers low energy and maximum entropy.
