Differential scanning calorimetry or DSC, is a common method for observing and quantifying the free energy of phase transitions (G).

Here typical DSC traces for first and second order phase transitions are overlaid in impasto over a backdrop of patterns. The connectivity and order in the background patterns are suggestive of the states of matter on either side of the phase transitions. The evolution of the patterns alludes to the order of the phase transition. The equations associated with free energy and DSC measurements are interspersed within the patterns, creating a textual counterpoint.

Phase transition order is determined by how the derivatives of free energy “G” are affected by the phase transition – and whether we should look at the first or second derivative to see the transition.
First order transitions have distinct DSC peaks, and the properties of matter change sharply. Second order phase transitions have more of a “step” shape with a point of inflection. The properties of matter change smoothly through a second order transition.
