  1. The lowest temperature theoretically
  2. possible, zero degrees kelvin, equivalent to
  3. -273.16 degrees C/-459.67 degrees F, at which
  4. molecules are motionless. Although the third
  5. law of thermodynamics indicates the
  6. impossibility of reaching absolute zero
  7. exactly, a temperature within 3 x 10^-8
  8. kelvin of it was produced in 1984 by Finnish
  9. scientists. Near absolute zero, the physical
  10. properties of some materials change
  11. substantially; for example, some metals lose
  12. their electrical resistance and become
  13. superconductive. See cryogenics.
