🔍 Key Concepts

• The difference between evaporation and condensation in the water cycle • What happens to water when it is heated to boiling versus cooled • The meaning of brine when dealing with seawater

💭 Think About

• When seawater is boiled, which part turns into vapor and which part is left behind? • Which term describes the phase change from liquid to vapor rather than from vapor to liquid? • In a distillation or desalination process, what is the first step that happens to the seawater when you apply heat?

✅ Before You Answer

• Identify which option describes liquid turning into vapor. • Eliminate any options that describe cooling or adding water, rather than removing it. • Confirm that the term you choose is commonly used in distillation/desalination processes.
