e)b only
Jessica--You REALLY need to work on these questions (this one and the one just before it). Start each sentence with a capital letter, place periods at the end of the sentence, AND read what you have typed to make sure it makes sense. For example, line two above, more less soluble makes no sense. Also, possible answer 2, gas bubbles may form and precipitate out. Gas bubbles may form makes sense but they don't precipitate.
1-sugar may precipitate out 2-gas bubbles may form and produce foam 3-water may evaporate out.
To determine what might happen when a soft drink (containing high concentrations of sugar and carbon dioxide) is cooled down, we need to consider the solubility of these components in water at lower temperatures.
As you mentioned, when temperature decreases, solubility generally decreases for gases and increases for solids in water.
1) Sugar precipitating out: Since lowering the temperature generally increases the solubility of solids in water, it is less likely for sugar to precipitate out when the drink is cooled down. Therefore, option 1 is unlikely to occur.
2) Gas bubbles may form and precipitate out: When the drink is cooled down, the solubility of carbon dioxide in water increases. This means that carbon dioxide is less soluble in cold water, and gas bubbles may start to come out of the solution, similar to how carbonation is released when a soda is left open. Consequently, option 2 is a possible outcome.
3) Water may evaporate out: Lowering the temperature does not directly influence the evaporation of water. However, depending on the conditions and the container, if the soft drink is exposed to a colder environment, water molecules may condense and form droplets on the outside of the container, giving the impression of water evaporating out. Consequently, option 3 is also a potential outcome.
So, the correct answer is:
d) b and c only
