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.
I think the friend will hear the bell the fastest in the air because sound waves can travel faster through air than through water, so the sound of the bell will reach the friend's ears more quickly in the air.
