Transcript

  • 1. CH 1-3 Measurement
  • 2. Scientific notation is used for very large or very small numbers 3.0 X 10 n
  • 3. SI units of measure
    • Scientist use a set of measuring units called SI or International System of Units
    • This helps scientist from different countries understand each others research
  • 4. Basic Units of Measure Candela- cd Luminous intensity Ampere- A Electric current Mole- m Amount of substance Second- s Time Kelvin- K Temperature Kilogram- kg Mass Meter - M Length
  • 5. Derived Units 2 3 2 2 2 2 2 m/s Acceleration (a) kg*m/s Force- Newton (N) kg*m/s Energy- Joule (J) m/s Speed (V) kg/m Density m Volume m Area
  • 6. SI Prefixes hundredth .01 c centi tenth .1 d deci thousand 1,000 k kilo million 1,000,000 M mega billion 1,000,000,000 G giga Meaning Multiple Symbol Prefix
  • 7. Limits to Measurement
    • Significant figures show how accurately something has been measured.
    • The precision of a calculated answer is limited to the precise measure with the least significant figures.
  • 8. Accuracy
    • Is the closeness of a measurement to the actual value of what is being measured
    • TEMPERATURE
    • To convert temperature to Kelvins you add 273 to C
  • 9. Problems
    • What is the boiling point of water in Kelvins?
    • Convert 12Kg to g
    • Convert 5mL to L
    • You get to school at 7:23 and leave at 3:45 how long were you at school?
    • You have a temperature of 101 F how many Kelvins is it?
