    A measure of the quantity of matter a body contains
  24. Define Weight
    A measure of the gravitational attraction of the earth for the body.
  25. Define Heat (2)
    • Heat - the energy that causes there to be changes in matter (measured in calories)
    • 1. amount of heat necessary to raise the temperature of one gram of water 1degree C
    • 2. calories= # of grams of water X # degrees change in temperature
  26. What is used to measure heat?
    Temperature
  27. What is used to measure temperature?
    Celsius and Kelvin
  28. Temperature is
    the hotness or coldness o
  29. Degree Celsius or Degree Centigrade
    Used in most scientific study
  30. Kelvin Scale
    • Used in many mathematical formulas of chemistry
    • -0 K is absolute zero
    • -an abstract number
    • -when all things in the universe come to a halt
  31. Conversion from Celsius to Kelvin(Absolute)
    K= C +273
  32. Conversion Kelvin (Absolute) to Celsius
    C= K - 273

    • Normal Body Temp. 37 310
    • Freezing point of water 0 273
  34. Define Energy
    The ability or capacity to do work
  35. Define Potential Energy
