It also shows the saturation pressure with changes in temperature.Īt the critical point there is no change of state when pressure is increased or if heat is added. The curve between the critical point and the triple point shows the propane boiling point with changes in pressure. The phase diagram for propane shows the phase behavior with changes in temperature and pressure. However, at low temperature and/or high pressures the gas becomes a liquid (or a solid at very cold conditions).
