FAQ

What is the Helmholtz Free Energy?
Helmholtz free energy is a thermodynamics concept in which, the thermodynamic potential is used to measure the work of a closed system. Helmholtz Free Energy is usually measured using the Kilojoule for Energy. Note that the value of Helmholtz Free Energy is always negative.
Can the Helmholtz Free Energy be negative?
Yes, the Helmholtz Free Energy, measured in Energy can be negative.
What unit is used to measure Helmholtz Free Energy?
Helmholtz Free Energy is usually measured using the Kilojoule[KJ] for Energy. Joule[KJ], Gigajoule[KJ], Megajoule[KJ] are the few other units in which Helmholtz Free Energy can be measured.
