Question: The Clausius-Clapeyron equation assumes the change in this to be zero. Because this quantity is most useful when the substance in question is both isothermal and isobaric, a different quantity is used for explosive substances. An equation partially due to the namesake of this quantity gives the temperature dependence of this quantity for an ideal gas. A zero change in this quantity for a system implies that the system is in equilibrium, but a negative value for this quantity implies that a reaction is spontaneous. One may derive this by utilizing the Legendre transform on the internal energy of a system. For ten points, name this state function named for its American inventor, which measures the maximum amount of work attainable from a system, defined as enthalpy minus the product of temperature and entropy.

Answer: Science


Question: This organ produces a tetrapeptide, which bonds to macrophage receptors, and is known as tuftsin. The sinusoids of one portion of this organ contain blood and a reserve of monocytes which can be utilized in the case of hemorrhagic shock. The other major portion of this organ contains Malphigian corpsules and synthesizes antibodies. Located in the abdominal region and consisting of red and white pulp, for 10 points, name this organ part of the lymphatic system that helps to filter and clean the blood.

Answer: Social Science


Question: The CIZA project determined that it only has 10% of its originally postulated mass, while Bertschinger and Dekel calculated the maximum Sachs-Wolfe anisotropy due to its effects. Partly responsible for the dipole anisotropy, it was originally discovered by a group later dubbed "The Seven Samurai". This structure is associated with a filamentous redshift phenomenon known as the Fingers of God. It was found due to irregularities in the Tully-Fisher relationship, resulting in peculiar velocities of up to 700 kilometers per second in several galaxies, and it contains the Norma and Abell 3627 cluster. It lies directly in front of the Shapley Supercluster and is core is located in giant filament of dark matter called the Great Centaurus Wall. Located in the Zone of Avoidance, for 10 points, name this object 250 million light-years across, named for its tendency to pull galaxies toward it.
