The interfacial tension between two surfaces is the difference in this quantity for those surfaces, and the derivative of the density of this quantity with respect to the deformation gradient gives the Piola Kirchoff tensor.
The interfacial tension between two surfaces is the difference in this quantity for those surfaces, and the derivative of the density of this quantity with respect to the deformation gradient gives the Piola Kirchoff tensor. This quantity is minimized at equilibrium in a system with fixed external parameters in thermal contact with a heat reservoir. Multiplying Boltzmann's constant with absolute temperature and the logarithm of the partition function gives the negative of this quantity. This quantity measures the amount of energy necessary to create a system once spontaneous energy transfer is accounted for, and equals the product of absolute temperature and final entropy subtracted from the internal energy. Commonly represented as A or F, for 10 points, name this quantity named after a German scientist, a form of free energy.
