Helmholtz Function

</dt>
A mathematically defined thermodynamic
function of state, the decrease in which during a reversible isothermal
process is equal to the work done by the system. the Helmholtz function is
where u is specific internal energy; T is Kelvin temperature; and s is specific entropy. By use of the first law of thermodynamics for reversible processes,
where dw is the work done per unit mass by the system. Also called Helmhotlz free energy, work function. Compare Gibbs function. [[/a>|/a> ]]
