The critical temperature and pressure of carbon dioxide (CO₂) are about 31.1 degrees Celsius (or 87.98 degrees Fahrenheit) and 73.8 atmospheres (or 1071 psi), respectively.

The critical temperature of a substance is the temperature above which it cannot be liquefied, no matter how much pressure is applied. This means that above this temperature, CO₂ cannot be converted into a liquid form, only a gas.

The critical pressure, on the other hand, is the pressure required to liquefy a gas at its critical temperature. This means that at 31.1 degrees Celsius, it would take a pressure of 73.8 atmospheres to convert CO₂ from its gaseous form to a liquid.

These values are significant because they are used in various industrial and scientific applications. For example, in the supercritical fluid extraction process, CO₂ is often used because its critical temperature and pressure values allow it to act as both a liquid and a gas, making it a good solvent.
