The pitch of sound changes when the water level in a glass changes because the frequency of the sound wave produced is directly related to the volume of air inside the glass. As the water level changes, it alters the volume of air present, which affects the frequency of the sound produced, leading to a change in pitch.
The change in sound as you fill a glass with water is due to the different densities of air and water. As the water level rises, the amount of air in the glass decreases, causing the transmission of sound waves to change. This results in a shift in pitch and clarity of the sound produced when tapping the glass.
A glass with less water will make a higher pitch when tapped, while a glass with more water will make a lower pitch. This is because the amount of water affects the frequency of vibrations produced by the glass when hit.
To create music using a singing wine glass, you can fill the glass with different levels of water to change its pitch. Gently run your finger along the rim of the glass to produce sound. Experiment with different amounts of water to create different notes and melodies.
The water level remains the same after the ice cube melts because the volume of the ice cube is already accounted for in the water level when it is frozen. When the ice melts, it simply changes state from solid to liquid without changing the overall volume in the glass.
When you pour water into a glass, the vibrations from the water hitting the glass walls create sound waves that we hear as sound. The pitch and volume of the sound can vary based on factors such as the speed of pouring, the material of the glass, and the amount of water in the glass.

The pitch is governed by the length of the column of air in the bottle, so you can change that by adding or removing a liquid like water. Are you blowing across the top or striking the bottle?
A glass of ice water is an example of a physical change, where water changes from a liquid to a solid state as it freezes. This change is reversible, as the ice can melt back into water.
Lower sound

The pitch of sound is higher in a half glass of water because the smaller amount of water leaves less space for sound to travel, causing the sound waves to bounce more frequently off the glass walls and create a higher frequency sound. In a full glass of water, the sound waves are able to travel more freely through the larger volume of water, resulting in a lower pitch.
When all the ice melts (it will take a while with the water at 0C), the water level in the glass will not be in any danger of overflowing the container because water is one of those rare liquids that expands when it freezes. (This is why a closed glass container of water put into a freezer will break.) This means that it contracts as it melts.The specific water level of the glass will depend on how much ice was floating above the water level, but it won't be in any danger of overflowing. As a matter of fact, the water level will actually be lower than the rim of the glass.
When the ice melts the water level will rise. The water level will increase because Ice is frozen water and when the ice melts, it turns to water, which means more water will be added to the glass.
I believe since the amount of evaporation and condensation in and out of the glass would be equal the amount of water would not change and the temperature would be equal since the enthalpy of the reaction is equal through the phase change. this is just my assumption. ps:are you in ess55 at uci?
No. It is a physical change.
The water level remains the same after the ice cube melts because the volume of the ice cube is already accounted for in the water level when it is frozen. When the ice melts, it simply changes state from solid to liquid without changing the overall volume in the glass.
