Symbol: A, F. Also called: Helmholtz free energy
Word origin
C20: named after Baron Hermann Ludwig Ferdinand von Helmholtz
Helmholtz function in American English
noun
the thermodynamic function of a system that is equal to its internal energy minus the product of its absolute temperature and entropy: a decrease in the function is equal to the maximum amount of work available during a reversible isothermal process
