Sound can travel through Liquids

We put a bell in it

We place our ear near water and ring the bell

We are able to hear the bell

This shows sound can travel through water

Sound can travel through Gases


If 2 people talk, sound travels through air, so we are able to hear


Sound cannot travel through vacuum

If we put our phone in tumbler and ring it, ring can be heard clearly

But if we suck air out of tumbler and then ring it, sound becomes fainter(less)

If we suck all the air, we will not be able to hear anything

This shows sound cannot travel through vacuum
