Evaporation and condensation rates are investigated for small clusters and nanoparticles in the presence of a gas by using classical molecular dynamics. The effects of the initial cluster temperature and size, as well as of the gas temperature and density are analyzed. The surrounding gas characteristics are found to strongly affect the cluster evolution. The obtained simulation results are analyzed based on the collision rate and on the Rice, Ramsperger, and Kassel theory.
