Seperation techniques

we can use distillation if the substances in solution are

• sublime

• volatile

• miscible

• flammable

a substance changes from solid to gas on heating. this is called

• distillation

• sublimation

• crystalization

• condensation

an oil refinery uses which process to separate the oils in crude oil.

• sublimation

• condensation

• distillation

• fractional distillation

if you shake a mixture of immiscible liquids what will happen immediately.

• it will become a cloudy solution

• it will become a cloudy mixture

• it will become a clear solution

• it will become a clear mixture.

ethanol and water can be separate using

• evaporation

• separating funnel

• fractional distillation

• fractionating column

which steps is not part of the technique to separate salt and iron filling from water

• use magnet to separate the iron filling

• evaporate the water

• filtering the salt

what happens when we keep a volatile liquid in a warm place

• it evaporates quickly

• it catches fire

• it solidifies into crystals

• it sublimes

if you shake a mixture of immiscible liquids what will happen to after sometime leaving it for ten minutes

• liquids separate and will form layers with the heavy liquid on top and lighter liquid on bottom

• it will become cloudy

• it will become clear

• liquids separate and will form layers with the light liquid on top and heavier liquid on bottom
