What is Helmholtz Free Energy?

In thermodynamics, the Helmholtz free energy is a potential value that measures the “useful” work obtainable from a closed thermodynamic system at a constant temperature.

Formula:

A = U - T*S

where,

• U  is the internal energy of the system
• T  is the absolute temperature
• S  is the entropy
• A  is the Helmholtz free energy
