Problem

A substance exists under two different sets of conditions. Condition 1: T=300 K,  P=2.0×10−3 atm;T = 300\,\text{K},\; P = 2.0\times 10^{-3}\,\text{atm}; average intermolecular separation ≈ 30 nm30\,\text{nm}; particles travel large distances between collisions. Condition 2: T=300 K,  P=50 atm;T = 300\,\text{K},\; P = 50\,\text{atm}; average intermolecular separation ≈ 0.30 nm0.30\,\text{nm}; particles translate only a few molecular diameters before colliding and remain in constant contact. Identify the phase of the substance under each condition and briefly justify each choice using the particulate information provided.
