in this video we're gonna learn about four methods for separating mixtures which are 00:00:00
evaporation filtration decantation and distillation evaporation is a method used 00:00:14
to separate homogeneous mixtures of a liquid and solid for example water and salt the mixture is 00:00:25
left in a dry place so that the liquid component evaporates and only the solid remains this system 00:00:44
is used industrially to extract salt from sea water filtration is a method to separate heterogeneous 00:00:52
mixers of a liquid and solid for example the oranges and the pulp the mixer is poured over 00:01:04
strainer or on porous paper called a filter the solid component will remain in the filter 00:01:13
whereas the liquid will pass through it decantation is a method to separate heterogeneous 00:01:30
mixers of two liquids, like water and oil. The mixer is left to stand so that the denser 00:01:41
liquid is at the bottom and the less dense at the top. Once this point is reached, one 00:01:51
of the two is removed from the container. Decantation can also be used to separate heterogeneous 00:01:58
mixtures of a liquid and a solid, like water and sand. 00:02:17
And finally, distillation. 00:02:38
This is a method to separate homogeneous mixtures of two liquids, like water and alcohol. 00:02:41
When heating the mixture, the liquid with the lowest boiling point will evaporate first. 00:02:49
In the case of wine, which contains water and alcohol, the alcohol will evaporate first 00:02:56
because it boils at 78 degrees, whereas water boils at 100 degrees. 00:03:02
This big tube here is filled with cold water. 00:03:10
When the gaseous alcohol goes through the spiral tube which is inside, it will be cooled 00:03:20
down and returned to its liquid state. 00:03:25
