    Go here and look at the electrical resistivity. Rinse and repeat.

    You've listed them in order. Are you quizzing us? [oops, not quite]

    thermal or electrical resistance?
    which grade/alloy? etc...

    Which of the following has the lowest resistance at 72 degrees
    silver,gold,copper or aluminum

    To determine that you need to specify the physical dimensions of each piece of the metal.

    He means Specific Resistance :)

    It's Silver, Copper, Gold, Aluminium in order of Increasing Specific Resistance.

    This order does'nt change over a very wide range of temperatures.

    The term "resistivity" is the more modern and widely accepted name. The term "specific resistance" is deprecated because the use of "specific something" is generally used to mean a dimensionless ratio.

    Not always, of course. Cleaning up terminology is a long, painful process that almost never succeeds completely.

    I made that comment, tongue in cheek. For the purposes of your question it makes no difference whether it's Fahrenheit or Celsius. ;)
