high pressure and low temperatures

At high pressure particle volume and collisions become important (deviating from the point-particle assumption), and at low temperature intermolecular attractions become significant (particles lose kinetic energy and may condense), so the kinetic‑molecular/ideal‑gas model breaks down.
