Question

What is helmholtz free energy?

Answer 1

Helmholtz free energy is a thermodynamic potential that estimates the helpful work reachable from a shut thermodynamic framework at a steady temperature and volume. The negative of the adjustment in the Helmholtz vitality amid a procedure is equivalent to the most extreme measure of work that the framework can perform in a thermodynamic procedure in which volume is held steady. On the off chance that the volume were not held consistent, some portion of this work would be executed as limit work. This makes the Helmholtz vitality valuable for frameworks held at steady volume.
