Jacob Zipperstein Reading Log Chapter 2 Data Analysis Section: 2.1 SI Units = Systeme Internationale d’Unites or Metric System Table 2-1: Quantity Base Units Time Seconds (s) Length Meter (m) Mass Kilogram (kg) Temperature Kelvin (K) Amount of a substance Mole (mol) Electric current Ampere (A) Luminous intensity Candela (cd) Table 2-2: G = giga = 10^9 M = mega = 10^6 k = kilo = 10^3 d = deci = 10^-1 c = centi = 10^-2 m = milli = 10^-3 u = micro = 10^-6 n = nano = 10^-9 p = pico =10^-12 Derived Units = Come from combining base units Examples – volume and density Volume = space occupied by an object. Units – cubic meter or cubic centimeter Liter = one cubic decimeter Density = mass/unit volume – ratio compares mass to an object’s volume Example – g/cubic centimeter Temperature – measures (approximately) how hot or cold an object is Kelvin – Freezes at 273k. Boils at 373k. + 273 to Celcius = kelvin
