A lab group designs an experiment to test which of four identical bottles will produce the sound with the highest pitch when air is blown across the opening at the top.

The pitch of the sound produced when air is blown across a bottle does not depend on the contents of the bottle but only on the size of the bottle. B. The highest pitches are produced when the total mass of air in the bottle is greater than the total mass of the water in the bottle. C. Sounds with the highest pitch are produced when all air is removed from the bottle. D. The pitch of the sound increases as the amount of air in the bottle decreases. 35.
