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 two sentences, make and justify a hypothesis on which medium the friend would hear the bell the fastest.

Answer 1

I hypothesize that the friend will hear the bell faster when it is rung underwater in the pool compared to in the air. This is because sound travels more efficiently through denser mediums like water than through the less dense medium of air, resulting in a shorter time for the sound waves to reach the friend.
