Phase Behavior
Pentane is a liquid at standard conditions. If heated above its boiling point of 36°C (97°F), it becomes a gas; when cooled below its melting point of -129.7°C (-201.4°F), it becomes a solid. The phase diagram shows that the critical point occurs at 469.8 K (196.7°C, 386.0°F) and 3.36 MPa, where no distinction exists between liquid and gas phases. The triple point occurs at 143.5 K (-129.7°C, -201.46°F) and 7.63 × 10⁻⁸ MPa, where solid, liquid, and vapor phases coexist.
