The phase diagram is a graphical representation of the physical states of a substance under varying conditions of temperature and pressure. A typical phase diagram has pressure on the y-axis and temperature on the x-axis. They contain a triple point - the point on a phase diagram at which the three states of matter: gas, liquid, and solid coexist; and a critical point - the point on a phase diagram at which you cannot tell the difference between the liquid and gaseous states of the substance. In contrast to the phase diagram of water, the phase diagram of CO₂ has a more typical melting curve, sloping up and to the right. The triple point is ?56.6°C and 5.11 atm, which means that liquid CO₂ cannot exist at pressures lower than 5.11 atm. You may use the phase diagram for CO₂ below as a visual reference. 11ec0fb7_280f_8461_95f0_7516497c23e2_NR0002_00
