Abstract
A simple assumption of the emergence in gas of small atomic clusters consisting of c particles each leads to a phase separation (first-order transition). It reveals itself by the emergence of a “forbidden” density range starting at a certain temperature. Defining this latter value as the critical temperature predicts the existence of an interval with the anomalous heat capacity behavior c p ∝ ΔT −1/c. The value c = 13 suggested in the literature yields the heat capacity exponent α = 0.077.
