Answer 2

Distillation desalination is one of mankind's earliest forms of water treatment, and it is still a popular treatment solution throughout the world today. In ancient times, many civilizations used this process on their ships to convert sea water into drinking water. Today, desalination plants are used to convert sea water to drinking water on ships and in many arid regions of the world, and to treat water in other areas that is fouled by natural and unnatural contaminants. Distillation is perhaps the one water treatment technology that most completely reduces the widest range of drinking water contaminants.

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. This process can be imitated artificially and more rapidly than in nature, using alternative sources of heating and cooling.

You can try this at home!

• Dig a pit in the ground

• Place a bowl at the bottom of the pit that will be used to catch the condensed water

• Cover the pit loosley with a plastic sheet (you can use stones or other heavy objects to hold it in place over the pit)

• Be sure that the lowest part of the plastic sheet hovers directly over the bowl

• Leave your water "trap" overnight and water can be collected from the bowl in the morning
