Avg score: 68% • Most missed: “Which of the following is an expression for Boyle’s temperature?”

Gas liquefaction involves cooling gas to a temperature below its boiling point so that it can be stored and transported in its liquid phase. Very low temperatures (known as 'cryogenic' temperatures) are required and these temperatures are achieved through a complex set of industrial scale processes.
