In the present paper we propose a simple and easy method to determine the latent heat of vaporization of pure water, using the Clausius–Clapeyron equation. The vapor pressure of water was calculated from measurements of temperature and volume, assuming an ideal gas behavior for the vapor. The calculated heat of phase change is in a good agreement with the latent heat of vaporization, obtained from the empirical Antoine equation and from the literature.
