As temperature rises, solids generally become more soluble in water, but gases become less soluble. If a soft drink contains high concentrations of sugar and carbon dioxide, which of the following may be expected to happen if it is cooled down? A) Sugar may precipitate out. B) Gas bubbles may form and produce foam. C) Water may evaporate rapidly.
I think this is a poor question because most of us know that sugar DOESN'T ppt when a soft drink is cooled. Of course, the question doesn't say how much it is cooled. At any rate, from the question, we know b can't be right an c can't be correct so that leaves only a. But I wouldn't EXPECT that to happen unless we cool it WAY down.
