Show Answers:

  1. the energy an object has because of its motion
    kinetic energy
  2. a theory explaining the states of matter, based on the concept that all matter consists of tiny particles that are in constant motion
    kinetic theory
  3. results from the force exerted by a gas per unit surface area of an object; due to collisions of gas particles with the object
    gas pressure
  4. a space where no particles of matter exist
  5. the pressure exerted by atoms and molecules in the atmosphere surrounding Earth, resulting from collisions of these particles with objects
    atmospheric pressure
  6. an instrument used to measure atmospheric pressure
  7. a unit of pressure; it is the pressure required to support 760 mm of mercury in a mercury barometer at 25°C
    standard atmosphere (atm)
  8. the SI unit of pressure
    pascal (Pa)
  9. the conversion of a liquid to a gas or a vapor
  10. vaporization that occurs at the surface of a liquid that is not boiling
  11. the temperature at which the vapor pressure of a liquid is just equal to the external pressure on the liquid
    boiling point (bp)
  12. the boiling point of a liquid at a pressure of 101.3 kPa or 1 atm
    normal boiling point
  13. the temperature at which a substance changes from a solid to a liquid; the melting point of water is 0°C
    melting point (mp)
  14. a solid in which the atoms, ions, or molecules are arranged in an orderly, repeating, three-dimensional pattern called a crystal lattice
  15. the smallest group of particles within a crystal that retains the geometric shape of the crystal
    unit cell
  16. one of two or more different molecular forms of an element in the same physical state; oxygen (O2) and ozone (O3) are allotropes of the element oxygen
  17. describes a solid that lacks an ordered internal structure; denotes a random arrangement of atoms
    amorphous solid
  18. transparent fusion product of inorganic materials that have cooled to a rigid state without crystallizing
  19. the process in which a solid changes to a gas or vapor without passing through the liquid state
  20. a graph showing the conditions at which a substance exists as a solid, liquid, or vapor
    phase diagram
  21. the point on a phase diagram that represents the only set of conditions at which all three phases exist in equilibrium with one another
    triple point
