The occurrence of many of these phenomena is accompanied by a sharp peak in heat capacity that looks like a lambda.
To study the behavior of these phenomena, Lev Landau introduced a mean field approach that uses the first few terms of a Taylor expansion. These phenomena often involve a spontaneously broken symmetry, which can be described by an order parameter. The occurrence of many of these phenomena is accompanied by a sharp peak in heat capacity that looks like a lambda. The lowest-order derivative for which the Gibbs thermodynamic potential is (*) discontinuous is used to classify these phenomena in the Ehrenfest classification. Systems undergo these phenomena in order to minimize the Gibbs free energy when a state variable, such as temperature, changes. When these phenomena are discontinuous, they have an associated non-zero latent heat. For 10 points, name these transitions in which matter transforms from one state to another, such as melting or evaporation.
