Physical Properties
Physical properties are things we can physically experience with our senses. Real-world example: Coloring on paper to change its color
Physical Changes: Changes in color, hardness, malleability, solubility, electrical conductivity, density, melting point, and boiling point.
Chemical Properties: Chemical properties are like the change from one type of matter to a different type. Real World Example: Burning a tree and creating smoke, and ash
chemical properties include flammability, toxicity, acidity, reactivity (many types), and heat of combustion.
Pure substances are substances that are made up of only one kind of particle and have a fixed or constant structure.
A mixture is a combination of two or more substances in any proportions.
Homogeneous mixtures
Heterogeneous Mixtures
A heterogeneous mixture is a mixture in which the composition is not *uniform throughout the mixture.
A homogeneous mixture is a gas, liquid, or solid mixture that has the same proportions of its components throughout a given sample.
Colloid
A colloid is a mixture in which one substance consisting of microscopically dispersed insoluble particles is suspended throughout another substance.
Example: smoke and dust in the air.
Example:Sugar water.
Example:Sand in water
Solution
A liquid mixture in which the minor component (the solute) is uniformly distributed within the major component (the solvent).
Elements
A chemical element is a chemical substance that cannot be broken down into other substances by chemical reactions. Elements are the things on the periodic table.
Compounds
A thing that is composed of two or more separate elements; a mixture.
