Introduction to Matter
•Matter is anything that has mass and occupies
space
• All substances around us are matter
• Matter can be pure substances or mixtures
3.
What is aMixture?
• Combination of two or more substances
• No chemical reaction between components
• Components retain individual properties
• Can be separated by physical methods
4.
Types of Mixtures
•Homogeneous mixtures: uniform composition
• Heterogeneous mixtures: non-uniform
composition
• Examples help identify the type
