WebFeb 22, 2016 · Imagine there is a container with a hypothetical boundary in the middle. Neon gas is on the left of the boundary, and Argon on the right. As long as the boundary exists, the gases can't cross it to intermix. Now the boundary is removed, and the gases mix. This increases the randomness in the system and thus entropy increases. We get $\Delta S ... WebFigure 16.10 The entropy of a substance increases (ΔS > 0) as it transforms from a relatively ordered solid, to a less-ordered liquid, and then to a still less-ordered gas.
