WebPentane is a liquid at standard conditions. However, if heated above 36°C/97°F it becomes a gas, and when cooled it becomes a solid. The phase diagram for pentane shows the phase behavior with changes in temperature and pressure. The curve between the critical point and the triple point shows the pentane boiling point with changes in pressure.
