Question

a) Name the separation method used in this process.
b) Which type of mixture is separated by the above process?
c) Which source of energy helps in converting sea water into water vapour?
d) Name any two components which are seen in sea water.​

Answer 1

Answer:

A) chromatography: Involves solvent separation on a solid medium. distillation: Takes advantage of differences in boiling points. evaporation: Removes a liquid from a solution to leave a solid material. filtration: Separates solids of different sizes.

B) Chromatography involves solvent separation on a solid medium. Distillation takes advantage of differences in boiling points. Evaporation removes a liquid from a solution to leave a solid material. Filtration separates solids of different sizes.

C) In nature, this basic process is responsible for the water (hydrologic) cycle. The sun supplies energy that causes water to evaporate from surface sources such as lakes, oceans, and streams. The water vapor eventually comes in contact with cooler air, where it re-condenses to form dew or rain.
