Hi,


Let's examine:
1.  At lower temps liquids can dissolve less solids.  That
     means that the liquid (of the soft drink) can "take" less
     solids then it could at higher temps - the result: The odd
     / extra quantity of sugar will precipitate (go out).
2.  Gas become more soluble at lower temperatures so when
     the temps decreases there is no problem..... In fact the
     liquid is then able to absorb even more gas than it contains...
3.  Water evaporates more as the temperature rises.... if the
     temperature decreases the opposite occours (less
     evaporation).
So the correct answer is 1.
Happy New-Year,
Love is the battery of life....

 Ions are electrically charged particles that are formed when certain compounds are dissolved in water. These solutions will conduct electricity. The Swedish scientist Svante Arrhenius coined the term ion (which means wanderer) to explain why solutions of electrolytes will conduct an electric current. When an electrolyte forms into a solution, it dissolves or dissociates into ions, a process called ionization. If a substance does not ionize, it will not conduct an electric current. Electrolytes include most acids, bases, and salts. Some conductors include hydrogen and sodium chloride, copper sulfate, and potassium nitrate. Substances that are not electrolytes include distilled water, sugar water, and most organic compounds. Which of the following is a nonelectrolyte?
