Entalpy and entropy role in freezing-point depression phenomena Yeah, I'm more interested in a "physical" explanation, rather than a mathematical one. But thanks, anyway. |

Eutectic systems behavior near 100%-0% composition and low temperature Thanks! That completely answers my question. However, what will happen if we were to lower even more the temperature of the almost-pure sample? According to the diagram it would turn into $\alpha$ + $\beta$, does it mean that the atoms of the low-concentration component would "get closer" until we could see some of them with the naked eye? How could this even happen at an atomic level if the high-concentration element particles have already organized into a solid body? |

Eutectic systems behavior near 100%-0% composition and low temperature Suppose we have a number of mixtures of $\alpha$ and $\beta$. If we pick one with a 99% concentration of, say $\alpha$ at a temperature above $\alpha$'s fusion point. When the temperature drops to below the L+$\alpha$ - Solid $\alpha$ equilibrium line, what happens? According to the diagram we have pure solid $\alpha$. Where does the other component go? |

How are constraint forces represented in Lagrangian mechanics? Did someone changed the title of the question? That is not what I'm asking, the original question was about the mathematical representation of these forces, the translation was a minor side question. |

Are Carnot engine efficieny and Fourier heat trasmission law related? I understand. However, they must both have a "cause" that explains them, don't them? Perhaps using statistical mechanics? My interest was if the causes or both phenomena could be traced back to a common one. |
