What are the critical temperature and pressure for\[\mathbf{C}{{\mathbf{O}}_{\mathbf{2}}}\]? What is their significance?

Answer:

                The critical temperature and pressure of \[C{{O}_{2}}\] are \[{{31.1}^{\circ }}C\] and \[\text{73}.0\text{ atm}\] respectively. Above this temperature, \[C{{O}_{2}}\] will not liquify even if compressed to high pressures.
