4. A. Common Units and Their Equivalents
Length
1km = 1000 m
1m =100 cm
1m =1000 mm
1nm= 1.0 x 10-9 m
Mass
1 ounce (oz) = grams (g)
1 pound (lb) = grams (g)
1 kilogram (km) = pounds (lb)
Volume
1 liter (L) = 1000 cubic centimeters (cm3)
1 mL = 1 cubic centimeters (cm3)
1 U.S. gallon (gal) = liters (L)
1 liter (L) = quarts (qt)
1 liter (L) = 1000 milliliters (mL)

5. B. Dimensional Analysis
The “Factor-Label” Method
Units, or “labels” are canceled, or “factored” out

6. B. Dimensional Analysis
Steps:
1. Identify starting & ending units.
2. Line up conversion factors so units cancel.
3. Multiply all top numbers & divide by each bottom number.
4. Check units & answer.

14. C. Thermometers
A typical thermometer is a calibrated, or numbered, glass tube containing mercury.
The silver mercury in the tube rises, or expands, when warmth of an object increases.

15. C. Thermometers There are three systems for measuring temperature.
Fahrenheit
Celsius
Kelvin

16. Fahrenheit.
The first scale is measured in degrees Fahrenheit.
The range from freezing point to boiling point on this scale is 32 to 212 degrees.

17. Celsius The other scale is measured in degrees Celsius.
. The range from freezing point to boiling point on this scale is 0 to 100 degrees.

18. Kelvin Scale, K • absolute scale (used for gasses)
• no negative numbers
• 0 K = absolute zero

19. Temperature Conversion Table
From
Fahrenheit (F o to C o)
(F - 32) * 5/9
Celsius (C o to F o)
(C * 9/5) + 32
Kelvin (C o to Ko)
C + 273

23. Generating a scatter plot
1. Determine and label X and Y axis
2. Highlight numerical data
3. Go to insert tab, click on chart icon
4. Click on scatter graph and Choose 1st scatter graph icon. (this will generate your graph)
5. Confirm your Y axis is being represented on the graph correctly (vertically). If it is go to the next slide and begin on step 7, if not continue with step 6
6. Click on design tab, and click on (switch row/column tab). Your data should now ne aligned correctly

24. Creating aTrend line 7. Click on a data point in the graph
9. Click on layout tab in chart tools
10. Click on more trend line options
Choose linear tend line, and click on display equation on chart, click close
Congratulations you just created an equation of the line.
Continue on next slide to label graph

25. Labeling a graph
11. In layout click on chart title icon, choose above chart and begin typing title, hit enter
12. In layout click on axis title icon, choose primary horizontal axis title. Click on Title below axis and begin typing the title, hit enter.
Make sure you put correct units in the title
