the number of bubbles produced the distance the filter paper rises the diameter of the filter-paper disks the time it takes for the filter paper to rise
Several different sized filter-paper disks are soaked in a solution and placed into another solution where a reaction will take place that produces a gas. The gas bubbles collect on the filter paper and make the filter paper rise to the top of the solution. Which of these is a measurement that would not be made during this experiment?

Options:
- the number of bubbles produced
- the distance the filter paper rises
- the diameter of the filter-paper disks
- the time it takes for the filter paper to rise
