🔍 Key Concepts

• Typical carriage temperature of Liquefied Natural Gas (LNG) in bulk transport • Difference between Kelvin (K), Rankine (R), Fahrenheit (F), and Celsius (C) scales • Relationship between Celsius and Kelvin (offset of 273 degrees)

💭 Think About

• First, recall roughly what boiling point / carriage temperature LNG is kept at to remain liquid at near-atmospheric pressure. • Which temperature scale is normally used in industry and training materials when quoting LNG carriage temperature? • Compare what happens if you subtract 273 from a Celsius value to express it in Kelvin—does "-160 K" make physical sense?

✅ Before You Answer

• Confirm which scale(s) can realistically have negative values for everyday temperatures (Fahrenheit and Celsius, but not Kelvin on an absolute scale). • Think about standard textbook figures: LNG is commonly stated to be around -260°F and around -162°C—which choice best matches that information? • Eliminate any answer whose units or temperature range would be physically impossible for a liquid at near-atmospheric pressure.
