  This paper is an expanded edition of the rapid communication published
several years ago by the author (Phys. Rev. B, v76, 041402(R), 2007) on the
simulation of wetting transition of water on graphite, aiming to provide more
details on the methodology, parameters, and results of the study which might be
of interest to certain readers. We calculate adsorption isotherms of water on
graphite using grand canonical Monte Carlo simulations combined with multiple
histogram reweighting, based on the empirical potentials of SPC/E for water,
the 10-4-3 van der Waals model, and a recently developed induction and
multipolar potential for water and graphite. Our results show that wetting
transition of water on graphite occurs at 475-480 K, and the prewetting
critical temperature lies in the range of 505-510 K. The calculated wetting
transition temperature agrees quantitatively with a previously predicted value
using a simple model. The observation of the coexistence of stable and
metastable states at temperatures between the wetting transition temperature
and prewetting critical temperature indicates that the transition is first
order.
