Statement 1: Hydrogen (Tc = 33 K) cannot be liquefied at 50 K, however high the applied pressure.
Statement 2: Above the critical temperature, the thermal (kinetic) energy of the molecules is too great for the attractive forces to hold them together in the liquid state.
Options:
Answer:
A
Solution:
Statement I is correct: 50 K > Tc = 33 K, so no pressure can liquefy H₂ at 50 K. Statement II is correct and is the reason: above Tc molecular agitation dominates over attractions, so a liquid phase cannot form at any pressure. II explains I. Ans: (a).
