Temperature (Sect. 8.2)
  • There are two common temperature scales:
    • Fahrenheit scale
      • Water freezes at 32º and boils at 212º
    • Celsius scale
      • Water freezes at 0º and boils at 100º

Temperature (Sect. 8.2)
  • What is Temperature?
    • Atoms are in constant motion, even in a solid object.
    • The back-and-forth jiggling of atoms is caused by thermal energy, which is a kind of kinetic energy.

Temperature (Sect. 8.2)
  • Temperature measures the kinetic energy per molecule due to random motion.
  • Average

motion leads to

a speed.

Random motion

leads to a temp.

Temperature (Sect. 8.2)
  • A thermometeris an instrument that measures the exact temperature.
  • Most thermometers contain either a silvery fluid (mercury) or a red fluid, which is alcohol containing a small amount of red dye.
  • How do they work?

Temperature (Sect. 8.2)
  • Absolute Zero? = -273ºC = 0 K
    • Uses the Kelvin (K) Scale
    • You cannot have a temperature lower than absolute zero.
    • Think of absolute zero as the temperature at which atoms are “frozen.”

To convert from Celsius scale to Kelvin scale, you just add 273 to your Celsius temperature.
