The critical temperature and pressure of a gas are 340 K and 42 atm, respectively. The gas can be liquefied at
Options:(select one or more)
Answer:
A, D
Solution:
A gas can be liquefied only at T ≤ Tc, and at T = Tc the applied pressure must be at least Pc. (a) T = 340 K = Tc with 45 atm > Pc: liquefiable ✓. (b) 40 atm < Pc at Tc: not liquefiable. (c) 350 K > Tc: cannot be liquefied at any pressure. (d) 320 K < Tc with a high pressure (42 atm): liquefiable ✓. Hence (a) and (d).
