1. Presentation Properties and Changes of Matter
By: Vaibhav Sharma

2. Matter
Anything that has mass and takes up space

3. Types of Matter Solid Liquid Gas Plasma Definite shape and volume
Takes shape of Container
Definite volume
Gas
Has no shape or volume
Plasma
Ionized gas – equal amounts of positive and negative atoms
Has properties different from gases
Excited molecules and free electrons

4. Other types of matter Superfluid Bose-Einstein Condensate
When liquids are close to absolute zero (-273 C)
Zero viscosity
Bose-Einstein Condensate
Matter in this form do not have independent particles

5. Properties of Matter

6. Physical Properties
Properties that can be observed without changing the sample
Examples:
Density – Mass/Volume (g/cm3
Color
Malleability – able to be pounded into thin sheets
Ductility – able to be drawn into wires

7. Intensive vs Extensive Properties
Intensive Properties do not changed based on amount of matter
Examples:
Density
Color
Extensive Properties change based on amount
Examples
Mass
Volume
Length

8. Chemical Properties Properties only observable when identity changes
Reactivity
Flammability
Only observed when something is burned
Oxidation
Apple turns brown when left in air
Can’t tell in advance without letting the apple change

9. Changes of Matter

10. Physical Changes
A change where the identity of matter remains the same
Phase Changes:
Solid to liquid -> melting
Liquid to gas -> boiling
Ice has same composition as water, water vapor
Can often be undone

11. Heating Curve

12. Phase Diagram

13. Chemical Changes Changes the identity of compound Wood Burning
Souring Milk
Caramelization of Sugar
Rust Formation
Copper turning green (patina)
