Analyzing Data Tables

The data table displayed shows the results of an experiment that was done to determine how fast sugar dissolves in 400 mL of water. Describe the relationship between Stir Speed and Time to Dissolve.

• As Stir Speed increases the Time to Dissolve increases.

• As Stir Speed increases the Time to Dissolve decreases.

• Stir speed does not affect the Time to Dissolve.

• Decreasing the Stir Speed will decrease the Time to Dissolve.
