Which of the following has the lowest resistance at 72 degrees

silver,gold,copper or aluminum

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

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

Is that Celsius or Fahrenheit?

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

Fahrenheit? Im just going to say it silver

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.
