🔍 Key Concepts

• Desalination methods used aboard ships (thermal vs membrane processes) • How a vacuum lowers the boiling point of water • Difference between flash evaporation and heating water inside tubes or across membranes

💭 Think About

• Which option names a process where water is suddenly exposed to a low-pressure (vacuum) space so that it rapidly evaporates? • Which of these units relies on boiling/evaporation rather than pushing water through a semi-permeable membrane? • Think about which designs usually involve multiple stages of rapid evaporation and condensation in distillation plants.

✅ Before You Answer

• Verify which unit type is typically described as a thermal, flash-evaporation distiller in marine engineering texts. • Check which option is not a membrane/filtration process (like reverse osmosis) but instead uses phase change from liquid to vapor. • Confirm which design specifically mentions a pressure drop into a vacuum chamber in its operating description.
