Separación por evaporación – Clip

The video explores the paradox of water abundance on Earth and the difficulty many face in accessing drinkable water due to salinity. It explains the natural process of desalination, where seawater is heated, causing water to evaporate and leave salt behind. The vapor is then condensed to produce salt-free, safe drinking water.

Why is it difficult for many people to find drinkable water on Earth?

• Because most water is salty

• Because all water is polluted

• Because water is scarce

• Because water is frozen

What is the first step in the desalination process?

• Filtering the seawater

• Freezing the seawater

• Cooling the seawater

• Heating the seawater

What happens to the salt during the desalination process?

• It evaporates with the water

• It stays behind as water evaporates

• It remains in the water

• It is filtered out

How is the water vapor turned back into liquid water?

• By freezing it

• By condensing it

• By filtering it

• By boiling it

What is the main benefit of the water obtained after desalination?

• It is more flavorful

• It is more abundant

• It is salt-free and safe to drink

• It is colder
