In general, solids tend to dissolve more readily in warm water than in cold water, but this can vary for different substances. Among the options provided:
A. Potassium chloride B. Sodium chloride C. Oxygen D. Sugar
Sugar (D) typically dissolves well in cold water compared to the other substances listed. While both potassium chloride and sodium chloride do dissolve in water, their solubility generally increases with temperature. Oxygen is a gas and its solubility decreases in warmer water.
Thus, the substance most likely to dissolve in greater quantities in cold water would be D. sugar.
