Speeds of sound of the elements

The speed of sound in any chemical element in the fluid phase has one temperature-dependent value. In the solid phase, different types of sound wave may be propagated, each with its own speed: among these types of wave are longitudinal (as in fluids), transversal, and (along a surface or plate) extensional.^[1]

Ref. CRC: Values are "at room temperature" unless noted, and "for normal atmospheric pressure" ("at 1 atm" for gases).
Ref. WEL: Values refer to 293 K (20 °C; 68 °F) "where possible". Midpoint values are substituted if ranges were given in their original reference. Not specified further, it is assumed from the values that all (except fluids) are for the speed of sound in a thin rod.
