Description	Předkládáme termodynamickou teorii zobecňující naše předchozí výsledky na případ klastrů s fluktuujícím počtem částic. V tomto případě dojde k fázovému přechodu díky změně velikosti klastru při procesu nukleace-evaporace. Vysvětlujeme odchylky závislosti teploty tání klastrů na velikosti klastru od klasických výsledků. (cs) Physics of phase transformations in finite systems has a long history, but there are many unresolved issues. Although there is a satisfactory qualitative picture of the phase transformations within an isolated small cluster, the experimentally observed dependence of the melting temperature on the cluster size contradicts the prediction of classical results. No clear physical picture of such a transformation exists for a condensed cluster in contact with gaseous environment. We propose a thermodynamic theory, which generalize previous results to the case of cluster with fluctuating number of constituent particles (open cluster). In this case, phase transition occurs because of size change during the nucleation/evaporation process. This allows us to explain the underlying physics of recent simulations and experiments. Although we used the grand canonical approach, our main results can be applied to isolated clusters. Particularly, we give simple arguments to explain the deviations of the cluster melting Physics of phase transformations in finite systems has a long history, but there are many unresolved issues.
