Re: [Phys-l] Definition of Substance

["R. McDermott" <rmcder@gmail.com>]

This is another place where definitions become strained.  A solution
consists of a solvent and solute.  For an alloy, it can become very
difficult to identify which is which.  Further, "solution" typically
refers to ONE solvent and ONE solute, where an alloy can certainly
consist of three or more elements.  Ditto for air, of course.
