90) 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?

1. Sugar may precipitate out.
   
2. Gas bubbles may form and produce foam.
   
3. Water may evaporate rapidly.
   

1. A only
2. B only
   
3. A and B only
4. B and C only
5. A and C only

The sugar becomes less soluble, and may come out of solution as a solid. The gas becomes more soluble and will remain in solution. If anything. the water will evaporate more slowly at lower temperatures.
