When you blow across the top of a bottle with water in it why does the frequency of the sound increase with increasing levels of water?
Blowing across the top of the bottle produces sound because the air oscillates inside the bottle. As you add more water, the air column inside the bottle shortens, leading to an increase in its natural frequency. This frequency increases as the air column becomes shorter, resulting in a higher pitch or frequency of the sound produced.

Why does water change the pitch of a bottle?
Well, honey, when you blow air across the top of a bottle, it creates vibrations inside the bottle. Adding water changes the size of the air column, which in turn changes the frequency of the vibrations and therefore the pitch. It's like playing a musical instrument, but with a plastic bottle instead.
Why is sound produced when you blow across a bottle?
When you blow across the opening of a bottle, you create a vibrating column of air inside the bottle. This vibrating column of air produces sound waves, which we hear as a tone. The pitch of the sound is determined by the size and shape of the bottle.
Why does the amount of water in a bottle affect the pitch when you hit it?
The pitch of the sound produced by hitting a bottle is determined by the frequency of vibrations in the bottle. When you change the amount of water in the bottle, you are changing the air volume within the bottle, which alters the frequency of the vibrations and hence the pitch of the sound produced.
What resonant frequency would you expect from blowing across the top of an empty soda bottle that is 18 cm deep if you assume it is a closed tube How would that change if it was one-third full?
For an empty soda bottle acting as a closed tube, the resonant frequency can be calculated as f = v / (4L), where v is the speed of sound and L is the length of the tube. Assuming room temperature (~ 343 m/s), the resonant frequency for an 18 cm deep bottle would be about 478 Hz. If the bottle is filled one-third full, the effective length of the air column increases, so the resonant frequency would decrease due to the longer effective tube length.
Where will the greatest increase in pressure occur if you squeeze the middle of an upright closed soft drink bottle?
The greatest increase in pressure will occur at the bottom of the bottle. When you squeeze the middle, you are decreasing the volume of the air inside the bottle, causing the pressure to increase. The bottom of the bottle will experience the highest pressure because it is the farthest point from where the force is applied.
What effects does an increase in frequency have on sound produced?
Wave length is smaller in high frequencies.. hence a higher pitched sound...Example, when you blow on the tip of a beer bottle, when its empty, the vibration travels all the way down the bottle and back up, hence a 'deeper' sound. the more you fill the bottle, the less room the vibrations have to move up and down the bottle, making the wave length much smaller, making the frequency higher, and the resulting sound higher pitched.

How do pipes work?
The noise is simply made by air vibrating down tubes of different lengths and diameters. Blowing across the tops of the tubes sets up a vibration. The frequency (pitch/note) is determined by the physical dimensions of the tubes. If you blow across the top of an empty bottle you will hear a note. Try blowing across the top of a different sized bottle, or a bottle partly filled with water and you will get a different note. Pan pipes are constructed to take advantage of this phenomenon.

Why might a bottle of hair spray explode if left in a hot car all day?
Increasing the temperature the pressure of the gas increase also.
What happens to the pressure in a bottle of water if you press the stopper at the top down farther?
Increasing the pressure on the stopper in a bottle of water will compress the air inside, which in turn increases the pressure. This will cause the pressure inside the bottle to rise. Conversely, releasing the stopper will decrease the pressure inside the bottle as the air expands.
How will you reduce drag forces in your bottle rocket?
the aerodynamics of the bottle can be increased or the bottle can be smoothened on all the sides therby increasing the aerodynamics therby decreasing the drag of the vehicle

When you shake a bottle what increases the pressure?
When you shake a bottle, the kinetic energy of the liquid molecules increases, leading to more frequent and forceful collisions with the walls of the bottle. This increase in collisions results in an increase in pressure inside the bottle due to the greater force exerted by the molecules on the walls.
How do you wean your baby pig from her bottle?
To wean a baby pig from her bottle, start by gradually diluting the milk with water over a period of time. Offer solid pig feed alongside the diluted milk to encourage the pig to transition to solid food. Slowly reduce the frequency of bottle feeding while increasing access to solid feed until the pig is fully weaned.
