Speed is that parameter which doesn't change.
Being a wave, sound can change its direction if it goes from one medium to another - for example, from air to water.
Water makes sound slower and if it goes through matter it goes faster
When a sound wave goes from air into water, its frequency remains unchanged. However, its speed will increase, and its wavelength will decrease due to the change in the medium's properties.
Water can absorb sound waves, reducing their intensity and making them less audible. Sound also travels faster in water than in air because water is a denser medium. Additionally, the presence of water can distort sound waves, causing them to scatter and become less clear or distinct.
Sound speeds up when it goes into water from air. Sound travels much faster in water than in air.
The energy that goes into temperature change is being used to change the state of the water, and until the transition is complete, it will not change temperature. The same goes for turning liquid water into a vapor. It is called the "latent heat", and sometimes "heat of fusion".
Temperature can affect sound pitch by altering the speed of sound waves in the air. In warmer temperatures, sound waves travel faster, resulting in a higher pitch. Conversely, in colder temperatures, sound waves travel slower, leading to a lower pitch.
It is called evaporation.
Because it does.
it goes from water (a liquid) to water vapor (a gas)! the 3 main physical states are solid, liquid and gas, so when it goes from one to another, this is defined as a physical change. you're welcome.
Yes, it gets bigger and some of the color goes into the water.
The density of water changes at different temperatures. As temperature goes up, density goes down.
