    2. 2 Chapter 2 Measurements in Chemistry

    3. 3

    4. 4 Using an instrument to determine data about the physical property of an object is a measurement.

    5. 5

    6. 6 Measurements are reported with a number and a unit.

    7. 7 Physical Properties

    8. 8 Three Important Physical Properties and the Metric System Base Units

    9. 9 Name the base unit for each physical property.

    10. 10

    11. 11

    12. 12 Be sure you know the metric system prefixes

    13. 13 Metric System Prefixes

    14. 14 Exact versus Inexact Numbers

    15. 15 Exact numbers can either be counted or they are defined as a standard reference. Inexact numbers are associated with numbers obtained from measurements.

    44. 44 Figure: 09-07 Title: solutions containing electrolytes conduct electricity Caption: A simple demonstration to show that electricity can flow through a solution of ions. Notes: (a) With pure water in the beaker, the circuit is incomplete, no electricity flows, and the bulb does not light. (b) With a concentrated NaCl solution in the beaker, the circuit is complete, electricity flows, and the light bulb glows.
