What is Duhem’s Theorem?
For any closed system formed from known amounts of prescribed chemical species, the equilibrium state is completely determined when any two independent variables are fixed. The two independent variables subject to specification may in general be either intensive or extensive. However, the number of independent intensive variables is given by the phase rule. Thus when F = 1, at least one of the two variables must be extensive, and when F = 0, both must be extensive.
How to Calculate Internal Energy using Helmholtz Free Energy, Temperature and Entropy?
Internal Energy using Helmholtz Free Energy, Temperature and Entropy calculator uses Internal Energy = Helmholtz Free Energy+Temperature*Entropy to calculate the Internal Energy, The Internal Energy using Helmholtz Free Energy, Temperature and Entropy formula is defined as the sum of Helmholtz energy and the product of temperature and entropy. Internal Energy is denoted by U symbol.
