Which of the following statements explains the phenomenon where gas 'A' liquefies under slight pressure increase while gas 'B' requires cooling even at high pressure?

Options

  1. AGas 'A' is at or below its critical temperature, and gas 'B' is at a temperature higher than the critical temp
  2. BGas 'A' is at a higher temperature than gas 'B,' causing it to liquefy more easily.
  3. CGas 'A' has a lower molecular weight than gas 'B,' making it more susceptible to liquefaction.
  4. DGas 'A' has a higher critical pressure than gas 'B,' leading to its liquefaction under slight pressure increas

Correct answer

A. Gas 'A' is at or below its critical temperature, and gas 'B' is at a temperature higher than the critical temp

Step-by-step solution

Correct Option is : (A) Gas 'A' is at or below its critical temperature, and gas 'B' is at a temperature higher than the critical temperature.
