What Is Sub Material?

  1. Apr 24, 2013 #1
    What is meant by the sub-material?

    Such as if you mix three differential materials, for example, coffee + sugar + water, which one them is the sub-material?

    Thank you

    I shouldn't even be in this thread, because I know almost nothing of chemistry, but I have to ask what you mean by "sub-material". I've never heard that term before.
    In the case that you cited, the water would be the solvent and the other two solutes. I guess that the solvent would be the liquid equivalent of a "substrate" such as the silicon in a microchip, but I somehow suspect that you refer to something else entirely.
