Meanings
- natural sciencesA measure of the useful work obtainable from a constant temperature, constant volume thermodynamic system; more precisely, the difference between internal energy (of a system) and the product of its absolute temperature and entropy.
A=U-TS where A is Helmholtz free energy, U is internal energy, T is temperature, and S is entropy.
Origin
For Hermann von Helmholtz, German physicist.
