Study Guide Chapter 1 - Foundations
1. SI Units what are the basic units see table 1.1
2. SI unit Prefixes See table 1.2 make sure you know:
M, k, d, c, m, :, n
6
(10 ,103, 10-1 ,10-2 ,10-3 , 10-6 , 10-9 )
3. Uncertainty
Difference between precision and accuracy
Significant figures
1. Counting sig fig
leading 0's don’t count
captured 0's do count
trailing 0's only count if after the decimal
Use exponential if any question
2. Sig Fig in calculations
+/Mult/divis
4. Unit conversion
Unit factor analysis
conversions that are good to know
1 lbs = 453.59g
1 L= 1.0567 qt
1 in = 2.54 cm
Temp conversion
only worry about K to oC and back
O
C = K - 273.15
5. Density
6. Classification of matter - Go through figure 1.13
