2. Would air be classified as matter or not?
What is Matter?
Matter is anything that is made up of particles, has mass, and takes up space.
Quick Question…
Would air be classified as matter or not?

3. Yes, indeed it is!
It wasn’t until 1654 in Germany that Otto Von Guericke showed that air is matter in an experiment.
Today, we can observe that air takes up space by blowing up balloons. We can compare the mass of air in the balloons with a balance.

4. Properties of Matter
Physical Properties – Characteristics of a substance that do not change the chemical makeup of the substance.
Chemical Properties - Characteristics of a substance that do change the chemical makeup of the substance. How a material reacts or fails to react in the presence of another material to form a new material.

5. Physical Properties of Matter
State of Matter
Melting Point
Boiling Point
Density
Conductivity
Uniformity
Texture
Strength
Bounce
Malleability
Luster
Conductivity
Elasticity
Odor
Taste

6. Some Physical Properties
State of Matter
Three common states are solid, liquid, & gas
Melting Point
When matter changes from Solid  Liquid
Boiling Point
When matter changes from Liquid  Gas
Density
Measurement of mass per unit volume
Conductivity
How well a substance conducts heat and electricity.

7. Can you identify the physical properties of matter by pictures?

8. MORE Physical Properties
Uniformity
The consistency of the substance throughout it
Texture
The feel of the surface of the substance
Strength
How well a substance withstands the application of a force
Bounce
Ability of a substance to rebound to its original position
Malleability
Ability of a substance to be hammered into various shapes without breaking or crumbling

9. Can you identify the physical properties of matter by pictures?

10. And Yet MORE Physical Properties
Luster
A substance that reflects light
Elasticity
A substance returns to its normal size and shape after a force has been applied and caused a deformation.
Odor
Some examples are sweet, foul, sour, etc.
Taste
Some examples are sweet, sour, salty, bitter, etc.
Typically not done in a science classroom

12. What are the States of Matter?
Solid
Liquid
Gas
Plasma
Bose-Einstein
**The three forms we commonly talk about are solid, liquid, and gas.**

13. States of Matter
1. SOLID: A solid has definite shape and definite volume. An example of a solid would be ice.
2. LIQUID: A liquid has shape defined by its container and defined volume. An example would be liquid water.

14. MORE States of Matter
3. GAS: A gas has undefined shape and undefined volume. An example of a gas is water vapor (steam).
4. PLASMA: Somewhat like gases. Are the most common state in the visible universe. (stars, lightning)
5. BOSE-EINSTEIN: Atoms at a very low temperature. They slow down so much they lose their individual identity.

15. Chemical Properties of Matter
Reactivity: The main classification of all chemical properties of matter.
Flammability
Combustion
Tarnishing
Hardening
Explosion

16. Some Examples of Chemical Properties
Rusting of iron on a bicycle when it is left out in the rain.
Iron + Oxygen  Iron Oxide
Combustion of coal
Tarnishing of silver
Hardening of cement
Explosion of dynamite
