What are the processes of Gibbs free energy? How does it work?

Please include links if you can. Help would be much appreciated!

Gibbs free energy simply combines entropy and enthalpy. Enthalpy accounts for changes in internal energy and work done by expansion. Suppose though that you opened a bottle of perfume and allowed it to evaporate to establish a liquid-gas equilibrium. Besides the work done by the expanding gas, there’s also the issue that you would have to expend energy to collect all those gas molecules together and put them back in the bottle. Gibbs free energy expresses this energy equivalence of entropy and adds it to the more familiar physical phenomena of temperature change and work.
