This separation technique separates two insoluble liquids with different densities.

• Decanting

• Magentism

• Filtering

• Evaporating and Condensing

Answer explanation

insoluble (not able to dissolve)

liquids

different densities

example: oil and water

In order to boil a liquid, you must

• add water

• add salt

• add metal

• add heat

Answer explanation

solids and liquids

no phase change (same states of matter)

This separation technique separates different sized solids.

• filtering

• decanting

• evaporating and condensing

• sieving

Answer explanation

solids

different size

Reorder the steps to separate a mixture of two solids which have widely different solubility in water.

• filter out the remaining solid

• add water to form a solution

• collect the remaining solid from the evaporated solution

• add heat to evaporate the solution
