Mixtures typically melt at different temperatures than the pure substances they are composed of. Brass is a mixture composed of copper and zinc, and it melts at temperatures between 820 degrees Celsius ( oC) and 1030 degrees Celsius ( oC). Why might different samples of brass melt at different temperatures?
