Benzene is a liquid at standard conditions. However, if heated it becomes a gas, and when cooled it becomes a solid. The phase diagram for benzene shows the phase behavior with changes in temperature and pressure. The curve between the critical point and the triple point shows the benzene boiling point with changes in pressure. It also shows the saturation pressure with changes in temperature.
At the critical point there is no change of state when pressure is increased or if heat is added.
The triple point of a substance is the temperature and pressure at which the three phases (gas, liquid, and solid) of that substance coexist in thermodynamic equilibrium.
