The critical temperature `(T_(C ))` and critical pressure `(P_(C ))` of `CO_(2)` are `30.98^(@)C` and 73 atm respectively. Can `CO_(2)(g)` be liquefied at `32^(@)C` and 80 atm pressure ?

Explanation

Critical temperature and pressure of `CO_(2)` gas are `30.98^(@)C` and 73 atm. This suggests that `CO_(2)` gas cannot be liquefied above `30.98^(@)C` and 73 atm howsoever high temperature and pressure may be applied on `CO_(2)` gas. Thus, `CO_(2)` gas can.t be liquefied at `32.^(@)C` and 80 atm.
