Liquefaction of Gases starts at 9 and continues till grade 12.
QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Liquefaction of Gases.
How you perform is determined by your score and the time you take.
When you play a quiz, your answers are evaluated in concept instead of actual words and definitions used.
See sample questions for grade 12

Describe the Linde process for the liquefaction of air.
Describe the main difference between the Linde and Claude methods for gas liquefaction.
Describe the significance of the critical point in the phase diagram of a substance.
Explain the role of pressure in the liquefaction of gases.
Explain why carbon dioxide forms dry ice instead of a liquid at atmospheric pressure.
Explain why hydrogen and helium are difficult to liquefy.
Explain why the Joule-Thomson effect is not observed in ideal gases.
