Study Guide – Chapter 2 Analyzing Data
Section 1 Units and Measurement
1. Time, Second
2. Kilogram, kg
3. Temperature, K
4. Meter, m
5. b
6. d
7. a
8. c
9. The correct order is: giga-, mega-, kilo-, centi-, milli-, nano-, pico-.
10. a. c; 1/100
b. k; 1000
c. m; 1/1000
11. Celsius; no, the SI unit for temperature is the kelvin.
12. 1000 g
13. 1,000,000 liters
14. 100 cm
15. Base units are defined units based on specific objects or events in the physical world. Derived units are defined by combining base units.
16. Density is a ratio that compares the mass of an object to its volume.
17. Canned goods are more dense than paper goods. They have more mass per unit volume. Thus, for the same volume, the canned goods have more mass than the paper goods. The greater mass is more difficult to lift.
18. Answers may vary. Students should note that density is defined as the mass of an object divided by its volume. Thus, algebraically, you can determine that an object’s volume is equal to its mass divided by its density.
19. analyze, solve, and evaluate
20. Add 273 to degrees Celsius.
