Thank you John and Paul for your replys to my question regarding sound waves and a vacuum. My student, however, had posed the
question with respect to our bell jar demo in the classroom. He understood that at great distances, the sound would invariably be
converted into heat before it reached the edge of our atmosphere. He wondered why the last layer of atoms on the bell did not fly
across the vacuum and strike the glass of the jar, and if not, what happens to the energy of the bell's motion?
