Which of the terms best describes the process of the production of vapor above the surface of a boiling cargo due to evaporation on an LNG tanker?

If the question has a related picture, it will appear here.

🔍 Key Concepts

• Behavior of liquefied natural gas (LNG) in insulated tanks • Definition of boiling vs. evaporation on cargo surfaces • Difference between vapor generation and phase change to solid or liquid

💭 Think About

• Think about what happens to LNG in a cargo tank that is kept very cold but not at absolute zero – does some of it still turn to vapor? • Ask yourself which option describes gas that forms and is collected as a normal part of carrying cryogenic cargo, rather than an abnormal or opposite process. • Consider which terms describe gas going FROM liquid TO vapor, and which describe the reverse or an unrelated phase change.

✅ Before You Answer

• Identify which choice refers specifically to vapor formed from a cold liquid cargo during carriage. • Eliminate any terms that describe liquid turning to solid or gas turning back to liquid. • Check which term is commonly used in LNG operations for vapor that may be used as fuel or must be managed/vented.
