The third law of thermodynamics states that entropy is zero at the unattainable lower bound of this quantity, known as absolute zero.
The change in the ratio of this quantity to Gibbs free energy is equal to the negative of enthalpy divided by this quantity squared. An engine's maximum efficiency is equal to one minus the ratio of this quantity measured at two different reservoirs according to Carnot's theorem. The energy of a blackbody is proportional to the fourth power of this quantity by the Stefan-Boltzmann law. Three-halves times this quantity times the Boltzmann constant equals a particle's average kinetic energy. The third law of thermodynamics states that entropy is zero at the unattainable lower bound of this quantity, known as absolute zero. For 10 points, name this quantity measured in kelvins.
