free energy

A thermodynamic quantity that is the difference between the internal energy of a system and the product of its absolute temperature and entropy. Free energy is a measure of the capacity of the system to do work. If its value is negative, the system will have a tendency to do work spontaneously, as in an exothermic chemical reaction. Free energy is measured in kilojoules per mole.
Also called Gibbs free energy

But Forrester blocked it; the splatter of free energy struck at the nearby trees, sending them crashing to the ground.

No wonder they hung around Durval's machines sucking up what free energy they could.

Thus the electromotive force is equal to the change of this free energy per electrochemical equivalent of reaction in the cell.

His physical vitality—his faculties of free energy, endurance, elasticity—was a superb endowment to begin with.

Another form in which to present these relations is to make a distinction between free energy and energy at rest.
