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.(2 points
The friend would hear the bell faster in the air compared to in the pool because sound travels faster in air than in water due to differences in the density and compressibility of the two mediums.
