free energy
- noun
- /fri ˈɛnərdʒi/
- Specialized
- For example, cell biologists need to understand entropy because free energy measures how much useful work can be done.
- Gibbs free energy
- free energy change
- free energy difference
So in order for reaction to be spontaneous, the free energy of that reaction has to be negative.
- So in order for reaction to be spontaneous, the free energy of that reaction has to be negative.
- We have incident energy and life evolved on Earth to capture, figure out ways to best capture that free energy to maintain itself and and grow.

And we know the total differential of Gibbs free energy from weeks past.
-
Both cases have the same initial total free energy; however, the no-flux boundary exhibits faster minimization of the total free energy.
Academic text (2018) -
To determine the wettability and surface free energy of the thin PyC films, the contact angle was measured.

To determine the efficiency of a chemical process, scientists often calculate the free energy of the reaction.
-
In thermodynamics, the concept of free energy helps predict whether a reaction will occur spontaneously.
-
The physicist explained how free energy is a critical factor in assessing a system's ability to perform work.

Morphology
The technical meaning (a specific variational/mathematical quantity in neuroscience and ML) cannot be derived by a B1 learner from the literal constituents 'free' and 'energy' — they would likely interpret it as 'energy that is without cost' or 'liberated energy'. Because the term is discipline-specific and abstract, its intended sense is idiomatic/technical and not predictable from the parts.
Etymology
The noun free energy in physics is the part of a system's energy that is free to do 'work'. So when free energy decreases there is less energy available and the system becomes more stable, which tells scientists if a reaction will happen 'on its own'.
