Abstract :     The ideal gas equation of state is the simplest equation of state for estimating the values of temperature, pressure and volume. This equation of state has a simple structure based on its simple theory. Hence, it has an explicit relation between these variables. In addition, calculating other thermodynamic properties insert ignore into journalissuearticles values(such as, internal energy, enthalpy and specific heats); is very simple for ideal gases. In this study, the ideal gas theory has been applicable for the liquid and vapor phases of water. To this aim, the temperature and molar volume have been modified as functions of the fluid molecular compressibility. In the presented method, effects of the temperature and volume on the non-ideality of the behaviors are considered, separately. Comparing the predicted values with the real data shows at least R-squared value equal to 0.98.
