A carbon dioxide cylinder has a volume of 0.15 m³ and is filled to 100 bar at 38°C. The cylinder cools to 0°C. What is the final pressure in the cylinder and how much more CO₂ can be added before the pressure exceeds 100 bar? If you add that much CO₂ to the cylinder at 0°C, what will the pressure be in the cylinder on a hot, 38°C day? What will happen if the cylinder can stand only 200 bar? [log (P_r^sat) ≈ (7(1 + ω)/3) (1 - 1/T_r)].
