One-dimensional systems with interactions restricted to first nearest neighbors admit a full ex-
act statistical-mechanical solution. When we switch on the interaction between second nearest-
neighbors particles the exact solution is suddenly lost. In this work we explore different approximate
solutions for second nearest-neighbor fluid models. And apply them to specific one-dimensional
fluids like the one with a square-well and a two-step pair-potential.
