In this task you will be given a text passage from a trivia quiz. You should choose the category this question belongs to from these categories: History, Science, Social Science, Fine Arts, Literature. You can only choose one category, so if in doubt, please choose the closest match.

This equation's accuracy can be improved if used in conjunction with Lorentz-Hudson-McCoubrey combining rules for modeling interactions between unlike molecules. The trace of fluid-solid coexistence curves can be performed by utilizing Kofke's method for this equation's associated integration. This relation can serve as a test for consistency for the Hubbard approximation if the external magnetic field and chemical potential are chosen as its two intensive parameters. The Lewis-Randall rule relates this equation to Henry's Law, and the Clausius-Claperyon equation can be derived from this relation assuming the two phases are in equilibrium. For 10 points, name this doubly eponymous equation that determines the relationship between changes in chemical potential for components in a system, named after a French energeticist and a Yale physicist.
Science

It begins in Scythia, in a locale characterized as "the world's limit an untrodden desolation. "  The title character doesn't speak until after Kratus and Bia, or Might and Violence, have left, soon after which he is visited by a Chorus of Ocean Nymphs, who like Hephaestus sympathize with the title character. It is to Oceanus that the title character recounts his tale, beginning with the war between the Gods and Titans. FTP, name this Aeschylus play about the tortured Titan whose foresight helped him give hope and fire to Man.
Literature

There is still dispute over the discovery of a Baragwanathia fossil that allegedly lived during this period, as it would indicate the presence of lycophytes during it. Its latter portion saw a temporary reduction in conodonts as part of the Lau event, which occurred before its Pridoli epoch. Baltica's collision with Laurentia resulted in the beginning of the Iapetus Ocean's closure during its Ludlow Epoch, and this period saw the emergence of the first coral reefs. Other developments include the evolution of the first freshwater fish as well as the proliferation of bony and jawless fish coinciding with its significant glacial melt. Also seeing the development of Cooksonia, the first vascular land plants, for 10 points, name this period during the Paleozoic era, in between the Ordovician and Devonian periods.
