Show transcript
The water in our seas and oceans contains salt. This water is not safe for drinking.
Evaporation can be used to remove the water from a salt solution.
Condensation is when a water in the gas state (water vapour) is cooled so that it changes to water in the liquid state.
Scientists and engineers investigate ways of making seawater safe to drink using evaporation and condensation.
Microorganisms must also be removed from water to make it safe to drink.
