 Notes 
 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 "where possible". Mid point 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.
