STUDY GUIDE Chapter 1: Matter, Energy Measurement

Define matter. Give examples of what is matter, and what is not matter Given a list of properties (or changes) distinguish chemical vs physical Memorize Element Symbols Scientific Method

o What does a hypothesis have in common with a theory?o Explain the process in which a hypothesis becomes a theory

NUMBERSo APPENDIX I Scientific (exponential notation)- Take numbers in and out. List numbers

in scientific notation in increasing (or decreasing) order

o APPENDIX IISignificant Figures SIG FIGS are for MEASURED numbers. Counted #s have INFINITE sig figs Count # of sig figs in MEASURED #s Rounding of sig figs Rules for reporting the Sig figs when ADDING/SUBTRACTING Rules for reporting the Sig Figs when MULTIPLYING/DIVIDING

o How to use Scientific notation to report Sig Figs precisely MEASUREMENTS

o Know if a given unit measures Length, Volume, Mass, Time, or Temperatureo Convert between Temperature Units (K, Celsius, Farhenheit)o Do Unit conversions by the Factor-Label Method

Review converting complex units (like mi/h to ft/s) Converting volumes like ft3 to cm3 (review meaning of cc and how a liter is

defined)

o Table 1.3 will be provided for you on the testo Metric System- you should be fluent converting units using the prefixes Kilo (k), deci (d),

centi (c), and milli (m)

States of Mattero Review compressibility of solids vs liquids vs gaseso Which states have definite shape?o Definitions of changes of state (vaporization, condensation, melting, freezing,

sublimation, deposition)

Densityo What can you tell about the relative densities of substances based on how they layer

themselves in a density column (see figure 1.6 in text)

o Calculations involving density. D=m/V Given two out of the three variables, solve for the third (Review how to solve for

V, MANY OF YOU HAD DIFFICULTY WITH THIS TYPE OF ALGEBRA)

Be prepared for questions that require you to reconcile the units
