When cooled, natural gas will become a liquid.

When cooled, natural gas will become a liquid.

• A. Depends on pressure
• B. Not sure
• C. False
• D. True

Answer: (D)

Natural gas can be turned into a liquid by removing enough energy through cooling. It’s mainly methane, and at cryogenic temperatures it condenses into LNG. At near atmospheric pressure the gas must be cooled to about -161 to -162°C for liquefaction. Pressure can alter the exact temperature needed, but the basic idea is that cooling a natural gas mixture below its boiling point at the given pressure will produce a liquid. So the statement is true.
