WebHelmholtz Equation is named after Hermann von Helmholtz. It is a linear, partial, differential equation. It is used in Physics and Mathematics. Its mathematical formula is : ∇2A + k2A = 0. Helmholtz Free energy can be defined as the work done, extracted from the system, keeping the temperature and volume constant.
In thermodynamics, the Gibbs free energy (or Gibbs energy as the recommended name; symbol ) is a thermodynamic potential that can be used to calculate the maximum amount of non-volume expansion work that may be performed by a thermodynamically closed system at constant temperature and pressure.
