This method is a technique used in separating a less-dense substance from a denser one.
decantation
evaporation
distillation
filtration
This technique is based on the differences of the boiling point of the substance in the mixture.

Which of of these mixtures could be separated by filtration?
sugar and milk
sand and water
milk and water
sugar and water
What mixture could I use this type of tool to separate?
oil and water
sugar and sand

pebbles and baby powder
You want to see what colors are all present in a solution. What method would you use?
chromatography
flotation
mangetism
sifting
You are using a sieve and pouring a flour and sugar mixture through it. Both substances pass through. Why is this?
They are the same size.
They have different masses.
This separates them easily.
They are the same color.
Which of the following best describes chromatography?
A solid is stirred in a liquid to make the solid float to the top.
A solution is heated until all the liquid turns to gas to leave a solid behind.
A solvent moves solutes up a paper based on how well the solute dissolves in the solvent.
A mixture of solids is put in a container that allows small particles to leave the container.
