Applications to Marine Disaster PreventionWe study in this chapter the phase diagrams of multicomponent systems. The representation that provides the simplest diagrams is that composed only by thermodynamic fields. A system of . components is described by . + 2 thermodynamic fields: the temperature ., the pressure ., and the chemical potentials .., .., ., .. of the . components.

Carnot Principle,When two bodies are placed in thermal contact, the hotter body gives off heat to the colder body. As long as the temperatures are different, there will be a flow of heat between them. After a while, the temperature becomes equal and the heat flow ceases. From that moment on the bodies are in thermal equilibrium.

GRILL

Clausius-Gibbs Principle,A system in thermodynamic equilibrium must be stable. This means to say that small perturbations do not remove the system from its equilibrium. In a mechanical system in stable equilibrium described by a potential energy ., the stability implies that the coefficient . is non-negative.

Nernst-Planck Principle,At sufficiently low temperatures, it is experimentally shown that the thermal capacity of the solids decreases appreciably and vanishes in the limit of zero absolute temperature. This behavior however does not necessarily follow from the laws of thermodynamics seen so far.

We notice that the fire is the most striking manifestation of the daily thermal processes. We learn that it can be used to heat water and make it boil and discover its enormous potentiality to genera

A gas is characterized by its high compressibility and low density. A solid and a liquid, in contrast, are less compressible, and have moderate or high densities. A solid, contrary to a liquid, off

This point which determines the end of the coexistence line and corresponds to the state in which the two phases become the identical, is called the critical point.
