In this letter, it is shown that the bulk cohesive energy $(E_{B})$ andbulk surface tension (\gamma) can be deduced from the size-dependent evaporation (SDE) study of free nanoparticles. The surface tension of nanoparticles $(\gamma_{n})$ is obtained by analyzing SDE data on the basis of the Kelvin equation, while $(E_{B})$ is obtained by reanalyzing the SDE data. By comparing the size-dependent melting and the SDE of nanoparticles, \gamma is evaluated.
