Do Now: Explain the difference between an intensive and an extensive property.
YWBAT
• Distinguish between a substance and a mixture.
• Differentiate between heterogeneous and homogeneous mixtures
• Explain how mixtures can be separated
Matter ClassificationMatter
Mixture Substance
Mixtures
• Mixture – a physical blend of two or more components
• Examples?
Mixtures
• Mixture – a physical blend of two or more components
• Examples– Salad– Chocolate chip cookie– Coffee with milk and sugar– Gasoline– Air

Mixture Substance
Heterogeneous Homogeneous
Heterogeneous Mixtures
• Heterogeneous Mixture – a mixture in which the composition is not uniform throughout.
• Examples– Salad– Chocolate chip cookie– Chicken noodle soup
Homogeneous Mixtures
• Homogeneous Mixture – a mixture in which the composition is uniform throughout.
• Another name for a homogeneous mixture is a solution.
• Examples– Vinegar– Air
Phase
• Phase– any part of a sample with uniform composition and properties.
• Homogeneous Mixtures – 1 phase• Heterogeneous Mixtures – 2 or more phases
Separating Mixtures
• Differences in physical properties can be used to separate mixtures
• Methods– Filtration – separates a solid from a liquid– Distillation – separates liquids based on boiling pt.– Magnetism
Filtration
• Filtration – the process that separates a solid from a liquid in a heterogeneous mixture
– Filter paper is placed in a funnel.– The mixture is poured into the funnel.– Solid particles that cannot pass through the filter
remain in the funnel.– The rest of the particles pass through.
Distillation
• Distillation – process which separates mixtures of liquids with different boiling points
