Q. 1
The critical temperature of gas in terms of Van der Waals constant
  • a. 3b
  • b. a/27b2
  • c. 2a/Rb
  • d. 8a/27Rb
  • e. a/bR
  • Answer: D

  • Explaination: Explanation: a- Van der Waals constant
    R-Universal gas constant
    b- Excluded volume
    Critical temperature is defined as the temperature above which a gas cannot be liquefied by applying pressure. It’s denoted as Tc. It can be expressed in terms of Van der Waals constant Tc = 8a/27Rb. It’s derived from the Vander Waals equation.
