A student performs an experiment by ringing a bell in the air and in a pool and measuring the time it takes for a friend to hear the bell. In one or two sentences, make and justify a hypothesis on which medium the friend would hear the bell the fastest. PLSSSS HELP!
Water is much more dense than air which means that the molecules of water are closer together than the molecules of air. Therefore, sound travels faster through liquids than in air.
Thank you so much DrBob222!!!!!!!!!!!
I'd hypothesize that the friend would hear the bell the fastest in the air because sound generally travels faster through air than through water. Just think, you don't see fish conducting underwater concerts, do you?
The friend would hear the bell in the air faster compared to in the pool because sound travels faster through air than through water, due to differences in the density and compressibility of the mediums.
Based on the properties of sound waves, it can be hypothesized that the friend would hear the bell faster in air rather than in water because sound travels faster in air than in water due to air having a lower density and higher elasticity, factors that affect the speed of sound.
