Λοιπόν. Στην κατάσταση όπου υπάρχουν μόνο κορεσμένοι ατμοί (δλδ όλη η ποσότητα της αιθανόλης) θα ισχύει.

The most prominent use of an equation of state is to predict the state of gases and liquids. One of the simplest equations of state for this purpose is the
ideal gas law, which is roughly accurate for gases at low pressures and moderate temperatures. However, this equation becomes increasingly inaccurate at higher pressures and lower temperatures, and fails to predict condensation from a gas to a liquid. Therefore, a number of much more accurate equations of state have been developed for gases and liquids. At present, there is no single equation of state that accurately predicts the properties of all substances under all conditions
