The critical temperature and pressure of a gas are 300 K and 50 atm, respectively. The gas can be liquefied at
Options:(select one or more)
Answer:
A, C
Solution:
Liquefaction requires T ≤ Tc, and at T = Tc the pressure must reach at least Pc. (a) 300 K = Tc with 55 atm > Pc ✓. (b) 310 K > Tc: impossible at any pressure. (c) 280 K < Tc with a high pressure ✓. (d) 45 atm < Pc at T = Tc: not enough. Hence (a) and (c).
