The entropy of one form of this process can often be determined using Trouton's rule. By Ehrenfest's classification of them, the lambda point occurs at a second-order one of these for Helium II. The Clausius-Clapeyron equation gives the slopes of the (*) coexistence curves on a diagram of this process. The changes in the temperatures at which this process occurs are two of the colligative properties of solutions. During this process, latent heat is released or absorbed. This process does not occur past the critical point. Types of it include deposition and sublimation.
