Hi guys,
We all know that Helmholtz free energy, Gibbs free energy and Enthalpy are defined by Legendre transformation.
For Enthalpy H=E+PV, I can understand it as the energy required to "displace the atmosphere" plus "creating the internal energy of system". What about Gibb free energy and Helmholtz free energy? What are their physical meaning?
