Sound cannot travel in vacuum. Describe an experiment to demonstrate this.

Experiment to demonstrate that sound cannot travel in vacuum:

Experiment 1:

We place a bell in an airtight jar and after ringing the bell, the sound is heard clearly. So it is proved that sound can travel in the air.

Experiment 2:

We place a bell in an air-tight jar that is connected to a vacuum pump. After ringing the bell we hear no sound. That proves that sound cannot travel in  vacuum.
