The critical temperature (T_(C )) and critical pressure (P_(C )) of CO

1.	The critical temperature (T_(C )) and critical pressure (P_(C )) of CO_(2) are 30.98^(@)C and 73 atm respectivelt. Can CO_(2)(g) be liquefied at 32^(@)C and 80 atm pressure ?
Answer» Solution :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.
