list gives the speed of sound in a number of different materials. Notice that for some
the temperature of the material is also given.

Some of these values vary widely
depending on the sources. For example the data given for aluminium varies from 5100
ms
-1 [the theoretical value ((E/
r)
1/2)] to 6240
ms
-1 in another practical based source.
