The model of one-dimensional gas is proposed in which the particles have hard cores and pair potentials -2a/L, a(>0) being a constant and L the length of the gas. The partition function for this model is exactly calculated and yields van der Waals' equation of state, involving an unstable portion of the isotherm. The grand partition function and the isothermal-isobaric partition function for this model are exactly obtained and a phase transition is deduced. Comparison of this model with the Husimi-Temperley model of a lattice system is made. The first five (volume-dependent) cluster integrals for this model are calculated.
