1. Good Vibrations

<BODY> <h2>1. Good Vibrations</h2><br> This program focuses on the particle theory of matter and how it helps to explain: 1) the behavior of solids, liquids and gases; 2) changes of state; 3) melting points and boiling points, using the example of train tracks to explain expanding metals; 4) the concept of absolute zero. Electron microscope images are featured; also we visit a balloon shop to look at why Helium is the preferred balloon gas, and where it comes from. 07DR JSCA 22 min. <A HREF="index.htm" target=_top>Home</a><br> </BODY>
