Using the lattice QCD equation of state for an isentropically expanding fireball we follow the evolution of the effective number of particles in an ideal gas, Neff = p V / T. This number reduces to its third around the crossover temperature, which helps to resolve the entropy problem inherent in hadronization models assuming quark coalescence.
