SUMMARY

The discussion focuses on the concept of phase transitions in thermodynamics, specifically differentiating between first-order and second-order phase transitions. The term "order" refers to the degree of differentiability of a thermodynamic potential when a physical parameter is varied to induce a phase transition. First-order transitions involve a discontinuity in the first derivative of the potential, while second-order transitions involve continuity in the first derivative but a discontinuity in the second derivative. This distinction is crucial for understanding the behavior of materials during phase changes.

PREREQUISITES

We often here the term in thermodynamics that a particular phase change is of 1st order , second order . What does the word order imply

It has to do with the order of differentiability of a thermodynamic potential when varying a physical parameter so as to cause the phase transition.

It is described here:
