Why is half-frozen fruit punch always sweeter than the same fruit punch completely melted?
(a) Because the sugar sinks to the bottom
(b) Because sugar molecules don’t crystalize with the water
(c) Because the half-frozen fruit punch is warmer
(d) Because sugar molecules precipitate as crystals
The correct option for why is half frozen fruit punch sweeter than melted fruit punch.
Answer to Problem 4RAT
The correct option for why is half frozen fruit punch sweeter than melted fruit punch is option (d).
Explanation of Solution
Liquids of different densities can be dissolved uniformly at lower temperature temporarily but as the temperature will decrease their solubility will also decrease.
When the Fruit punch is half melted, the water content if frozen and rest melted part is the syrup which is rich in flavour and sugar content. When the fruit punch is completely melted the water comes up and the sugar syrup is no more uniformly dissolved in water. As the sugar syrup has higher density it will settle at bottom, as a result the sweetness of fruit punch will be lost.
Conclusion:
Therefore, the correct option is option (d).
