🔍 Key Concepts

• Distillation vs. evaporation – what each term means in a seawater distillation plant • The meaning of brine in a distillation system • The meaning of distillate in freshwater production from seawater

💭 Think About

• For each option, ask yourself: does this describe the correct definition of the key term being used (distillation, evaporation, brine, distillate)? • Think through the actual sequence in a seawater distillation plant: what happens first, what is produced, and what by‑product remains? • Which choice correctly matches both the process and the product with the right technical term?

✅ Before You Answer

• Be sure you know that brine is the more concentrated leftover seawater, not the purified product. • Confirm that distillate refers to the fresh water obtained from condensed vapor, not to the water that remains behind. • Verify which step involves boiling/evaporation of seawater and which step involves condensation of vapor.
