Some
important materials, such as water and
silicon, expand upon freezing. The diagram shows a surface of state
for water.
· In this case also, the two phase zones project onto the (p, T) plane as single lines separating (p, T) regions in which a single phase exists. · Along these lines the two phases on either side are in thermodynamic equilibrium and have the same value of their Gibbs function. · In any single phase zone of the (p, v, T) surface, the equilibrium phase is that of lowest Gibbs function. In the two phase zones, both phases have the same Gibbs function. |
