In thermodynamics, the Helmholtz free energy is a thermodynamic potential that measures the “useful” work that can be performed by a system at a constant temperature and volume. The Helmholtz free energy is named after the German physicist Hermann von Helmholtz.

Q: What is Helmholtz free energy and Gibbs free energy?
A: The Helmholtz free energy, also known as the Helmholtz function, is a thermodynamic potential that measures the “useful” work that can be performed by a system at a constant temperature and volume. The Gibbs free energy, also known as the Gibbs function, is a thermodynamic potential that measures the “useful” work that can be performed by a system at a constant pressure and temperature.
Q: What is Helmholtz free energy in statistical mechanics?
A: The Helmholtz free energy is a thermodynamic potential that measures the “useful” work that can be performed by a system at a constant temperature and volume. The Helmholtz free energy is also known as the “work function” or the “free energy of formation”.
Q: What is Helmholtz energy used for?
