For 10 points, name this quantity, which measures  the amount of disorder in a system.
This quantity for an ideal gas can be calculated by the Sackur-Tetrode equation, while another  equation uses this quantity, temperature, and enthalpy to calculate Gibbs free energy. The Third  Law of thermodynamics states that its value at absolute zero is zero. Symbolized as S, this  quantity has a unit of joules per kelvin, and according to the Second Law of Thermodynamics,  this quantity will always increase over time.
