The entropy of a system is another thermodynamic quantity that is not easily measured.

Consequently, from the partition function we can obtain the average thermodynamic quantities for the ensemble.

The above values can be used to calculate other thermodynamic quantities.

Once the Gibbs free energy is known, many thermodynamic quantities can be determined as first- or second-order derivatives.

One can also use D-branes to compute a thermodynamic quantity called free energy.

This also signifies that the amount of heat absorbed at constant volume could be identified with the change in the thermodynamic quantity.

Each of these iso-lines represents the thermodynamic quantity at a certain constant value.

It is possible to envision three-dimensional (3D) graphs showing three thermodynamic quantities.

Since the system is at equilibrium, the (Gibbs) free energy (a thermodynamic quantity) of each phase is also exactly the same.

This is certainly true in terms of the thermodynamic quantity called "enthalpy", which is another way to account for energy.
