Critical temperatures of ammonia and carbondioxide are respectively 405.5 and 304.1K. Cooling from 450K, which gas can be liquify first? Why?

Critical temperatures of ammonia and carbondioxide are respectively 40

1.	Critical temperatures of ammonia and carbondioxide are respectively 405.5 and 304.1K. Cooling from 450K, which gas can be liquify first? Why?
Answer» SOLUTION :AMMONIA gas can be liquified FIRST, Because the CRITICAL temperature of ammonia will be reached first, Liquification of CARBONDIOXIDE will require more cooling.
