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?

• 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
