A thermodynamic system is described by a number of macroscopic parameters.
From the
| extensive parameters | intensive parameters |
| \(N, V, S, U, ...\) | \(\mu, p, T, ...\) |
| proportional to the size of the system | independent of the size of the system |
pairs are formed
| \(N\) | \(\mu\) |
| \(V\) | \(p\) |
| \(S\) | \(T\) |
| \(\vec{M}\) | \(\vec{H}\) |
| \(\vec{P}\) | \(\vec{E}\) |
| \(...\) | \(...\) |
always one parameter of this pairs is used to describe the system.
