2. NGSS Florida Standard SC912P8.2
Differentiate between physical and chemical properties and physical and chemical changes of matter

3. What are Physical Properties?
Physical property = characteristic that can be observed without changing the identity of the substance.
Properties of an object are determined by the properties of the materials the object is made of

4. Measurable properties
Strength
Hardness
Magnetism
Ability to conduct heat
Ability to conduct electricity

5. Which Physical Properties Depend on Amount
Mass
Volume
Area

6. Which Physical Properties Do Not Depend on Amount
State of matter
Melting point
Boiling point
Density

7. About Melting Point and Boiling Point
State = the physical form of a substance
Melting Point = temperature at which a substance changes from a solid to a liquid
Boiling Point = temperature at which a substance changes from a liquid to a gas

8. Density The amount of matter in a certain volume of a substance
Density = mass/volume
On your whiteboard, calculate the density for a 10.0cm3 of ice that has a mass of 9.17kg.

9. How would you answer? What determines the properties of an object?
What are two physical properties of an object that depend on the amount of material you have?
What is a state?
What is the density of 10kg mass of water?
How would you rearrange the density equation to show how to find the mass of a substance if you know the volume and density?
If a piece of metal has a density of 11.3g/cm3 and a volume of 6.7 cm3, what is the mass of the metal?

10. Density vs. Weight
Weight = exertion of gravity upon matter; linear measurement
Density = concentration of mass in a given volume; derived measurement

11. What Are Chemical Properties?
Chemical property = how a substance changes into a new substance
Not as easy to observe as physical properties
Substances combine or break apart

12. Examples of Chemical Properties
Flammability = the ability to burn
Nonflammability = the inability to burn
Reactivity = ability of a substance to react with another substance

13. More About Reactivity Reactive elements are usually found as compounds
Less-reactive elements are more likely to be uncombined.

14. Which type property is it?
Material or object
Observation
Physical or chemical property?
Chalk
Forms bubbles when put into vinegar
Ice cream
Melts in the sun
Tin
Bend easily
Paper
Burns quickly
Liquid water
Evaporates
Car door
Starts to rust
Helium balloon
Floats in air
