Understanding Distillation

Why is distillation necessary in countries like Saudi Arabia?

• Because they have an abundance of freshwater sources.

• Because they have limited rainfall and need to purify seawater.

• Because they have a lot of industrial waste.

• Because they have a high population density.

What is the role of the condenser in the distillation process?

• To separate salt from water.

• To heat the solution.

• To measure the temperature of the solution.

• To cool the water vapor and turn it back into liquid.

Which two main processes are involved in distillation?

• Filtration and evaporation.

• Evaporation and condensation.

• Condensation and filtration.

• Sublimation and evaporation.

What happens to the ink particles in the distillation of inky water?

• They evaporate with the water.

• They are collected in the condenser.

• They remain in the round bottom flask.

• They dissolve in the pure water.

What is a major disadvantage of using distillation for obtaining drinking water?

• It produces a lot of waste.

• It requires a lot of energy, making it expensive.

• It cannot remove salt from seawater.

• It is a very slow process.
