under which conditions will sugar most likely dissolve fastest in a cup of water?\n a sugar cube with stirring at 5°c\n a sugar cube without stirring at 15°c\n sugar crystals with stirring at 15°c\n sugar crystals without stirring at 5°c
Answer
Explanation:
Step1: Consider surface - area effect
Increasing the surface - area of the solute increases the rate of dissolution. Sugar crystals have a larger surface - area compared to a sugar cube as they are in smaller pieces.
Step2: Consider temperature effect
Higher temperature generally increases the rate of dissolution as it provides more kinetic energy to the molecules. 15°C is a higher temperature than 5°C.
Step3: Consider stirring effect
Stirring helps in bringing fresh solvent in contact with the solute and removes the saturated layer around the solute, thus increasing the rate of dissolution.
Answer:
sugar crystals with stirring at 15°C
