"History of thermodynamic potentials" 1.a) Take a couple of thermodynamic potentials (Gibbs free energy, Helmholtz free energy, entropy, enthalpy, internal energy, etc.). What is their current physical meaning? 1.b)How and whom they were introduced in physics (the history). Consider the original circumstances and initial meaning. 1.c). How the understanding of these thermodynamics potentials has been changed with time (from thermodynamics to statistical physics). Provide a few practical applications from chemistry, biology, engineering, etc. where the knowledge of thermodynamics potentials are absolutely necessary.
