A student performs an experiment by ringing a bell in the air, and then 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 bail the fastest
The student may hypothesize that the friend would hear the bell fastest in the air rather than in the pool. This is because sound travels faster in air than in water due to differences in their densities, resulting in faster sound propagation.
