Mo5-L1c: Matter: How to Identify a Substance?

Key Concept Sorting Materials Using Properties
Matter: How to Identify a Substance? Physical properties and chemical properties are
useful for sorting materials.
How are properties use to identify a substance?

Separating Mixtures Using Physical Properties

Physical properties, such as a material’s melting
point, are useful for separating different types of
matter that are mixed.
