This quantity equals the negative partial derivative of the grand potential with respect to temperature. Ignoring the indistinguishability of particles leads to a non-extensive form of this quantity in the Gibbs paradox. Like temperature, the Carnot cycle contains two steps in which this quantity (10[1])is constant. (-5[1])This quantity was defined as proportional to the (-5[1])natural logarithm of the number of microstates (10[1])by Ludwig Boltzmann. (10[2])The “arrow of time” is defined because this quantity (10[1])is non-decreasing for isolated (10[2])systems by (10[1])the Second Law of Thermodynamics. For 10 points, name this quantity that is informally the amount of disorder in a system. (0[1])■END■
