States of Matter
What are the 3 states of matter?
What are the properties of the states of matter.
Solid, Liquid, Gas
Summary: Finish in Class
Solid
Retain fixed volume; rigid particles locked into place.
Definite volume.
Not easily compressible; little free space between particles.
Definite shape.
Does not flow easily; does not expand when heated.
Particles vibrate or move slowly; does not move from place to place
Liquid
Assumes shape of its container; particles slide past one another. Indefinitie volume.
Slightly compressible; some space between particles.
Indefinite shape.
Flows easily; expands some when heated.
Vibrates; particles move past one another linearly.
Gas
(Vapor)
Assumes shape of its container; particles move past one another fast.
Indefinite volume.
Easily compressible; lots of free space between particles. Indefinite shape.
Flows easily; expands a lot when heated.
Particles move fast at high speeds and no pattern to movement.

What is the 4th state of matter?
What is the microscopic view of each state?
Plasma
Partially Ionized Gas; free electrons are not bound to an atom or molecule.

Summary (finish for homework or in class if time permits)

15. Percent Error Percent Error: (Accepted Value – Measured Value) x 100
Example: Accepted value = 1.2
Measured value = 1.3
(1.2 – 1.3) x 100 = 8.3 %
1.2
Actual Density of H2O = 1.00 g/mL

16. Steps of Inquiry Ask a QUESTION Make a PROCEDURE Interpret RESULTS

Using data to:

17. Quiz (10 pts)
What is the volume of water in the graduated cylinder? Measure to 2 figures (numbers)

18. Density volume (mL) Density is a physical property of matter.
Defined as the amount of mass per unit of volume.
Density = mass (grams)
volume (mL)

19. Reading Graduated Cylinders
Graduated cylinders are used to measure volume of liquids.
How much liquid is the graduated cylinder?

20. Reading Graduated Cylinders
Graduated cylinders are used to measure volume of liquids (in mL).
How much liquid is the graduated cylinder?
The curved line is the meniscus. Read the volume from the bottom of the curve.
The volume of the liquid is 35 mL.

21. Reading Graduated Cylinders
Graduated cylinders are used to measure volume of liquids (in mL).
To read, find the lines labeled with numbers
Count the steps between
Divide
10/10 =1
Every tick mark is 1mL

22. Reading Graduated Cylinders
Read at the meniscus
10/10 =1
Every tick mark is 1mL
Volume = 35 mL
1/5 = 0.2
Every tick mark is 0.2 mL
Volume is 6.2 mL

23. Types of Data Data does not equal scientific evidence
Previous knowledge + DATA = Scientific Evidence
Qualitative Data: information that describes color, odor, shape, or some other physical properties
Quantitative Data: Numerical information that tells you how much, how little, how big, how tall or how fast.
Data Tables organize data for display and understanding.

24. September 14, 2009 Today’s Goal: AGENDA: HOMEWORK:
To understand the importance of lab safety and lab safety rules
HOMEWORK:
Complete lab safety worksheet
AGENDA:
1 – Quick Chem and Discussion
2 – Get in lab groups
3 – Safety Activity
4 – Data and Data Tables
5 – Wrap Up

25. Data Table Data Tables display data
Previous knowledge + DATA = Scientific Evidence
Qualitative Data: information that describes color, odor, shape, or some other physical properties
Quantitative Data: Numerical information that tells you how much, how little, how big, how tall or how fast.

26. Understanding Lab Safety
You should NEVER try to taste any of the substances.
You should ALWAYS wear your lab goggles. Some of the lab materials are skin, eye irritants.
Always dispose of the laboratory materials appropriately.
Wear appropriate clothing and shoes.
REMEMBER the class rule: FOLLOW DIRECTIONS!
