Question

93. Which of the following gases require minimum temperature for its liquefaction? (A) Argon (B) Oxygen (C) Nitrogen (D) Water vapour​

Answer 1

Answer:

water vapour is the answer

Answer 2

liquefaction

Explanation:

• Higher the intermolecular forces, higher the temperature for liquefaction
• Hydrogen has the least intermolecular forces while ammonia has the highest intermolecular force.
• Hydrogen  has  the least temperature for liquefaction.
• Temperatures for liquefactions are as follows.
• Ammonia = -33°C
• Hydrogen = -252.8°C
• Nitrogen= -147°C
• Argon= -186°C
