MIXTURES AND SOLUTIONS

• A mixture is a nonchemical combination of two or more substances.
• In other words, the substances can be separated by physical means like heat and friction.

TYPES OF MIXTURES

• There are two main types of mixtures, heterogeneous mixtures and homogeneous mixtures (solutions).

HETEROGENEOUS MIXTURES

• If the particles in a mixture consist of clumps of atoms or molecules, especially if the clumps are very large, it is is heterogeneous. The term mixture by itself usually refers to a heterogeneous mixture.
• The two types of heterogeneous mixtures are Colloids and Suspensions.

COLLIODS

• Colloids contain small clumps of atoms.
• The colloidal particles scatter light.
• Examples: jelly, marshmallows, and paint

SUSPENSIONS

• Suspensions contain large clumps of atoms.
• The particles will eventually settle out creating, a layer of sediment at the bottom of the mixture.
• Examples: salad dressing and sand in water

SOLUTIONS

• The solute is evenly distributed in the solvent in a solution.
• Particles do NOT settle at the bottom of the mixture in a solution.
• Examples: salt water, syrup, and bronze

BIBLICAL INTEGRATION

• You are a mixture.
• You may have little or large clumps of stress, anxiety, and depression that people can see.

BIBLICAL INTEGRATION

• You are a solution.
• You may have stress, anxiety, and depression, but people don't see it.

BIBLICAL INTEGRATION

• No matter which one you are, you have problems that need to be fixed.
• God is the only one who can remove these problems from you.
• Just we use heat and friction to separate the substances, God uses the Holy Spirit to separate us from any problem we might have.
