What results from gas particles no having a strong attraction to one another?

The Ideal Gas law assumes minimal interaction between gaseous particles. Each molecule is considered to behave independently, and undergoes MINIMAL interaction with other molecules. And even with molecules that possess significant intermolecular interaction, for instance gaseous water, $H C l \left(g\right)$, $N {H}_{3} \left(g\right)$ under given conditions, i.e. low pressure, and high temperature, the ideal is largely maintained.
