In an experiment, Ryan filled a beaker with 100 mL of liquid and heated it up 1 point
to 100°C. Next, 20 mg of solute was crushed and added to the beaker. The
mixture was then stirred for 1 minute and allowed to sit for 10 minutes.
Which of the following adjustments could Ryan have made to dissolve his
solute even faster?*
Crushing the solute into bigger chunks
Raising the temperature of the solvent to 50°C instead of 100°C.
Resting the mixture for 7 minutes instead of 10 minutes.
Stirring the mixture for 3 minutes instead of 1 minute,
