The aim of this investigation is to reconsider the classical theory of homogeneous condensation and bubble nucleation by including real properties of fluids and dissipative effects. To find out the influence of a chemical composition on the surface tension and consequently on the nucleation work and further to elucidate how the nucleation barrier is affected by the including of irreversible processes on the bubble surface. Both these phenomena are important for the nucleation and it is shown that they can increase (for condensation) and decrease (for boiling and cavitation) the nucleation work. The derived theory is suitable both for pure substances and for their mixtures. The emphasis is laid to the water condensation, boiling and cavitation.
