Why does the doppler effect result in different pitch shift in water than it does in air? a) because sound is not able to travel through liquid. b) because the air particles are closer together than the  liquid particles. c) because sound travels faster in a liquid d) because the liquid particles are closer together than the air particles .

- The intensity of a sound wave depends not only on the pressure of the wave, but also on the density and sound speed of the medium through which the sound is traveling.

- Sounds in water and sounds in air that have the same pressures have very different intensities because the density of water is higher than the density of air and because the speed of sound in water is much greater than the speed of sound in air.

- For the same pressure, higher density and higher sound speed both give a lower intensity.

So the correct answer is:

D) Because the liquid particles are closer together than the air particles 

The gas would begin to expand, and eventually the can would burst or explode.
