Chemistry Vocabulary: Measuring Matter

  1. matter: the stuff that makes up everything in the universe. Anything
    that has mass and takes up space.
  2. properties (of matter): ways to describe or categorize matter.
    Hardness, texture, shape, temperature, flammability, size, and colore
    are all examples of properties of matter.
  3. characteristic properties (of matter): a quality of a substance that
    never changes and can be used to identify unknown substances (ex.
    Boiling point and melting point).
  4. chemical reactivity: the ability of a substance to undergo a specific
    chemical change. This is a characteristic property.
  5. boiling point: the temperature at which a substance boils (the boiling
    point of water is 212 degrees Fahrenheit or 100 degrees Celsius). This
    is a characteristic property.
  6. melting point: the temperature at which a substance melts. This is a
    characteristic property.
  7. density: the measurement of how much mass of a substance is
    contained in a given volume. D = m/v
  8. mass: a measure of how much matter is in an object.
  9. weight: a measure of the force of gravity on an object.
  10. volume: the amount of space that matter occupies.
  11. International System of Units (“SI”): the system of units used by
    scientists to measure the properties of matter.
  12. states (of matter): the three traditional states of matter are solids
    (fixed shape and volume) and liquids (fixed volume and shaped by the
    container) and gases (filling the container); “the solid state of water
    is called ice.”
