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.

Earthworms uniquely use the molecule lombricine to react with this molecule. This molecule activates P2X3 and P2X2/3, two receptors that control pain responses, and in conjunction with luciferin this molecule is responsible for the light of fireflies. In the muscular tissue of chordates, this compound donates a group to creatine. In proteins, this molecule, first synthesized by Alexander Todd, is almost always bound by a magnesium cofactor, and large quantities of this molecule are produced via oxidative phosphorylation in the electron transport chain. For 10 points, name this molecule discovered by Karl Lohmann,, the energy currency of the cell.

Section 9 concerns the reason of animals, while the views of Epicurus concerning the gods are defended in section 11, "Of a particular providence and of a future state. "  The final section treats the "academical or sceptical philosophy," though the better known sections deal with miracles, the association of ideas, and the idea of necessary connection. FTP, name this 1748 book, in which David Hume reworked the first part of A Treatise on Human Nature, not to be confused with an essay by Locke.
