I looked it up-Second Law: The amount of usable energy in the universe is steadily decreasing, while the level of disorganization is steadily increasing. ... in all natural processes some potential energy (organized energy) is always converted to kinetic energy (disorganized energy, usually in the form of heat). So your answer should be usable energy
If there is less water in the bottle, then the note played is lower because there is more air to move around.
Using two different media (air and water) in glass bottles show how the speed of vibrations affects pitch.
Pitch is the way that your ear and brain order sounds based on their frequency (vibrations per second).
Rapid vibrations (high frequency) that reach your ear are categorized as a "higher" pitch, while slower vibrations (low frequency) are categorized as a "lower" pitch.
When you tap a glass of water with a pencil or spoon the water molecules vibrate and create sound waves through the water. More water means slower vibrations and a deeper tone.
The bottle with the most water will have the lowest pitch while the bottle with the least water will have the highest.
When Wanda and Marita blow across the top of the bottle, they set the air molecules vibrating and produce sound waves. In this case, more water results in a higher pitch, as opposed to tinkling the bottle. When the bottle has a small amount of water in it, the air molecules have lots of room and vibrate slower. Adding more water gives them less space to vibrate in, making them vibrate faster and producing a higher pitch.
