Group Y is presumed to have achieved a quicker dissolution of the salt. This conclusion is based on the technique they employed—stirring vigorously for 1 minute, which increases the agitation and facilitates the dissolution process. In contrast, Group X stirred gently for the same duration, which is likely to result in slower dissolution. The choice of a spoon versus a cup for adding the salt is less likely to have a significant impact on the dissolution speed compared to the difference in stirring intensity.
Two sets of students engaged in a competition to determine which group could achieve the fastest dissolution of 5 grams of salt in 50 mL of water. The table illustrates the techniques they employed.
Group X:
Step 1: Measured 50 mL of water into a 200 mL graduated cylinder
Step 2: Added 5 grams of salt with a cup
Step 3: Stirred gently for 1 minute
Step 4: Recorded the time with a stopwatch
Group Y:
Step 1: Measured 50 mL of water into a 100 mL graduated cylinder
Step 2: Added 5 grams of salt with a spoon
Step 3: Stirred vigorously for 1 minute
Step 4: Recorded the time with a wristwatch
Which group is presumed to have achieved a quicker dissolution of the salt?
3 answers
so which group?
Group Y would be presumed to have achieved a quicker dissolution of the salt due to their technique of stirring vigorously, which facilitates faster mixing and dissolving compared to the gentle stirring used by Group X.
