First-Order Phase Transformation at Constant Volume: A Continuous Transition?

  title={First-Order Phase Transformation at Constant Volume: A Continuous Transition?},
  author={V{\'i}ctor F. Correa and Facundo J. Castro},
We describe a first-order phase transition of a simple system in a process where the volume is kept constant. We show that, unlike what happens when the pressure is constant, (i) the transformation extends over a finite temperature (and pressure) range, (ii) each and every extensive potential (internal energy U, enthalpy H, Helmholtz energy F, and Gibbs energy G), and the entropy S is continuous across the transition, and (iii) the constant-volume heat capacity does not diverge during the… 



The Ehrenfest Classification of Phase Transitions: Introduction and Evolution

Abstract The first classification of general types of transition between phases of matter, introduced by Paul Ehrenfest in 1933, lies at a crossroads in the thermodynamical study of critical
