Therefore, in a finite reversible isothermal process the total work done on the
system by the surroundings is equal to the increase in the Helmholtz function of
the system. Conversely, when the system does work on the surroundings in a ...

Thermodynamics: Concepts and Applications
We will revisit this property later in this chapter in the discussion of ideal-gas
mixtures; in Chapter 6 this property is prominent in the discussion of chemical
equilibrium. Helmholtz Free Energy or Helmholtz Function The Helmholtz free
energy, ...

Furthermore, since daT : P dvT, (7.23') the reversible isothermal work or area
under an isotherm on a P-v diagram represents the Helmholtz function. The work
transfer during an isothermal process results in a change in the Helmholtz
function.

where Cg and G, are values of the Gibbs function for saturated gas and saturated
liquid, respectively. For the region (tk — r)<0.5°C an exact solution for the
Helmholtz function subject to Eqs. (A.7) yields values of density for the saturated
liquid ...

Energy and Finite Element Methods in Structural Mechanics
Let us now consider another function used in thermodynamics called the
Helmholtz function, F, defined as a specific value in the following way: F = u - Ts
Since u, T, and s are point functions, F must be a point function. Now consider a ...

An introduction to thermodynamics
The work delivered is less than the decrease in the Helmholtz function, if there is
any irreversibility present in the process. Since the decrease in the Helmholtz
function represents the potential to do work by the system, it is also a ...

In addition to internal energy and enthalpy, there are at least two other important
fundamental thermodynamic functions, namely the Helmholtz function, also
called free energy, and the Gibbs function, also called free enthalpy. Why do we
have ...
