Nia is given a salad dressing mixture of oil and water and is asked to separate the mixture into its

separate parts.

How should Nia separate these substances, based on their physical properties?

O She should leave the mixture alone and let it settle so that the oil and water

will separate; then, she should decant the oil.

She should warm up the mixture to cause one of the substances to melt out

of the it; then, she should freeze it in a separate container.

O She should shake the mixture to cause the substances to separate based on

the different sizes of their particles.

O She should boil the mixture to cause one of the substances to evaporate
