To make a tea cup, we add hot water, this method is called:

(a)  

Mixture separation are methods that provoque a:

• Physical change

• Chemical change

• Chemical reaction

• Phase change

Sieving is a mixture separating method used to separate solids. We can do it at home using a:

• Filter paper

• Washer machine

• Fridge magnet

• Strainer

Filtration is a method used to separate:

• A liquid from a gas

• A solid from a liquid

• A gas from a liquid

• A solid from a solid

Not all the mixtures can be separated using Crystallization method. This is because:

• Not all the substances can be separated

• Not all the solutes can form crystals

• Not all the solvents can form crystals

• Not all the substances can sublimate

• FALSE: Some mixtures need two or more methods to get separated.

• TRUE: All the mixtures can use all the methods, you decide the one you want to use.

• FALSE: The mixtures can't be separated.

A mixture is formed by:
