Question

write the physical significentbof Helmholtz free energy and Gibss free energy​

Answer 1

Answer:

In thermodynamics, the Helmholtz free energy is a thermodynamic potential that measures the useful work obtainable from a closed thermodynamic system at a constant temperature and volume (isothermal, isochoric).

Gibbs free energy is a measure of the amount of energy available to do work in an isothermal and isobaric (constant temperature and pressure) thermodynamic system. This is where the term "free" comes from; it refers to the amount of energy in a system that is easily available for usage.
