Chapter 3 The Metric System
§3.1 – Introduction • Systems • Imperial system • Metric system (SI) • Use in industry • Table 3.1 (p. 125) • Table 3.3 (p. 126) • Problems 3.1 #2, 10, 14, 20, 32, 36
§3.2 thru 3.3 – Length and Mass • Length (meter and other units) • Problem 3.2 #40, 44, 54, 56, 62 • Mass (gram and other units) • Problem 3.3 #36, 44
§3.4 – Volume and Area • Volume • Liquid measurements • Spatial measurements • Figures 3.10 and 3.11 (p. 133) • Liquid units – Liter (and other) • Do problems 3.4 #8, 40 • Spatial units – m3 (and other) • Do problems 3.4 #10, 45 • Volumes / mass relationships • 1 g = 1 cm3 = 1 mL • Ex: How many mL in 0.5 m3? What is the mass of 0.5 m3?
§3.5 – Time, Current, & Power • Time – seconds (other units) • Problem 3.5 #26 • Current (Amp and other) • Power (Watt and other) • Problems 3.5 #16, 32
§3.6 – Temperature • Temperature scales • Celsius, Kelvin, Fahrenheit • Water boils (100⁰C, 373K, 212⁰F) • Water freezes (0⁰C, 273K, 32⁰F) • Conversion formulas • Convert 42.3⁰F to Celsius • A child has a temperature of 37⁰C. Is the child running a fever?
§3.7 – Metric and US Conversions • Need for conversion in industry • Conversion section of reference card in book • Problem 3.7 #2, 18 • A common engine size in late 1970s model Pontiac Firebirds used to be 305 in3. By the late 1980 models a common size was 5.0L. Is there a significant difference in these engine sizes? • Graded Activity #4
