Resumen de The Meaning of Δ
It is suggested that the Δ terms for state variables in thermodynamics be arranged in a hierarchical order, because it simplifies terminology and resolves a discrepancy in the use of Δ between chemistry and other disciplines. A term higher in the hierarchy can be used for any lower term but with loss of some information. An example, commonly said to be a mistake, is the use of Δμ or Δrμ in place of the derivative ∂G/∂ξ.
