Answer:
Accuracy decreases
Explanation:
All meaurements have an uncertainty (That is, the error of the measurement). The uncertainty of graduated cylinders is higher than uncertainty of pipets.
The accuracy is how close is the measurement to the real value.
If you use graduated cylinders rather than pipets, <em>accuracy decreases </em>because you will have more uncertainty in the measurements putting of the real value and the real value.
