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
