A simple modification of the well-known two-term equation of state is proposed. The modification makes it possible to extend considerably the range of applicability of this equation of state and improve the accuracy of the results of calculation of thermodynamic quantities obtained by means of this equation, in particular, of such important parameter as the temperature. An example of constructing the modified two-term equation of state for water is given.
