Question: It exists because of electron degeneracy pressure; as electrons are compressed closer together, more exist per unit volume and must take on higher energy levels as mandated by the Pauli-exclusion principle. A relativistic state equation can be used to calculate it as the radius of a white dwarf decreases with an increase in its mass. Developed shortly before its namesakes theory on black holes, for ten points, name this value of about 1.4 solar masses, the maximum mass of a star which can be supported against gravitational collapse.

Answer: Science

Question: It is equal to the enthalpy change minus the temperature times the entropy change. Under standard conditions, it is also equal to negative R T times the natural log of K, where R is the gas law constant, T is the absolute temperature, and K is the equilibrium constant for the reaction; thus a high negative value indicates a forward-going reaction. FTP, identify this quantity, named for a Yale chemist, which is a measure of the spontaneity of a reaction.
