Balloons can make some fun noises when you pinch and stretch the opening as you let the air out! The reason a balloon makes a higher pitch when you pull tighter comes from the amount of movement allowed. Because the air pushes through the opening of the balloon against the tightened rubber, this rubber vibrates as it gets pushed apart and pushes back together against the air. The tighter this opening, the less leeway the rubber has to move, and the faster it will vibrate, causing a higher pitch.

How do your vocal cords produce different pitches?
By varying their tension, tighter = higher pitch.
Is a broken balloon a physical or chemical change?
Physical, because the balloon did not have a change in its chemical composition when it broke.
Is Carbon dioxide filled with balloon a chemical change?
No. helium is released in outer air but does not lose or change its chemical formula

Yes, It is a physical change because it's only losing air. when you put air in the balloon it's still a balloon, and when it loses air it's still a balloon. So it's a physical change since it didn't change in substance.

The tighter the string is, the higher the pitch is. You probably shouldn't experiment with that though, as strings break surprisingly easy.
How does your voice change pitch?
The pitch of your voice is determined by the tension in your vocal cords, which can be adjusted by muscles in your larynx. When your vocal cords are stretched tighter, they vibrate faster and produce a higher pitch. Conversely, when they are more relaxed, they vibrate slower and produce a lower pitch.
How does the tightness of guitar string affects the note it produced?
it changes the pitch, tighter strings produces higher pitch..
What happens when you tighten a guitar string by turning its keys what pitch will you make?
The tighter you make the string - the higher the pitch.
What factors create a higher pitch?
tighter tension and shorter air dome

Is breaking a balloon a physical change?
Yes, it is a physical change. Nothing chemically changed about the balloon.
What causes the pitch on an electric guitar?
it is due to the tightness of the strings , they are tightened to a certain pitch as the faster the string moves the tighter it has been tuned.
Is a broken balloon a physical or chemical change?
