Cards (29)

  • Energy determines the state
  • extensive property
    one that Does depend on the amount of the substance present.
  • Intensive property
    One that DOES NOT depend on the amount of the Subtance present.
  • Boiling point / condensation point
    the exact temperature at which liquid becomes a gas or gas to liquid.
  • Melting Point /freezing point
    the exact temperature at which a solid beccomes a liquid or a liquid become a Solid.
  • State (phase) of matter
    solid, liquid, gas Plasma
  • Malleability
    Ability of a subtance tobe hammered flat and to retain
  • Ductility
    Ability of a substance to be stretched into a wire
  • luster
    the way that a substance reflects light (metalic non-metallic, glassy. pearly, dull).
  • highest density element
    Osmium 23 g/cm3
  • Lovest density Element
    Hydrogen 0.0009g/cm3
  • Density
    the ratio of mass to volume reflects the degree of packing of particles in matter.
  • Volume
    The amount of space an space object occupies (in ml, L, cm³,m etc)
  • Mass
    the amount of matter in an object (in g or kg).
  • Temperature
    A measure of the average kinetic energy (energy of motion) of of particles subtance
  • Texture
    how the substance looks and feels.
  • color
    how the object absorbs and reflects light
  • Physical property
    A trait of matter that can be observed or measured without changing the chemical composting of the matter.
  • Changing states
    state change
    phase change
    Physical change
  • Add or subtract Energy
    -when evergy is added, particles move faster
    -When energy is taken away, particles move slower?
  • Particles in Plasma
    • Are electrically charged
    • Have extremely high energy levels.
  • Plasma
    • lightning is a plasma
    • Used in fluorescent light bulbs and Neon lights
    • Plasma is a lot like a gas, but the particles are dectically charged
  • Gasses
    • Gasses spread out to fill the entire
    • space given and do not have definite volume
    • Gasses have mass
    • Gasses take up space
  • Particles in liquids
    • Are loosely packed
    • Have medium energy levels
    • particles flow around each other
  • liquids
    • liquids take the shape of their container and have definite volume • liquids have mass
    • liquids take up space.
  • Particles in Solids
    • Are packed tigthly together.
    • Have verry little energy.
    • vibrate in place
  • Solids
    • Solids have definite shape and definite Volume
    • Solids have mass.
    • Solids take up spaces.
  • Matter
    is anything that has mass and takes up space
  • particles in gases move freely, have lots of energy
