A diffusion model for the evaporation of a single spherical droplet is examined taking into account the reduction in the droplet temperature and vapor pressure near its surface, for arbitrary condensation and surface tension coefficients. Quite general analytical expressions for the dependence of the lifetime of a droplet on its initial radius are derived for the first time. This model makes it possible to estimate the condensation coefficient of the vapor molecules from the experimental form of this dependence.
