精选优质文档-倾情为你奉上不同温度和压力下的声速The classical ideal gas law may be written as pV=nRT, from which the expression for gas density relating to pressure p could be deduced: =pM/RT, wherein V and n correspond to volume and number of moles of a substance, respectively; T, M and R are respectively corresponding to absolute temperature, molar mass and ideal gas constant, approximately 8. J/(molK).The sound speed of sound in an ideal gas depends only on its temperature and composition. The spee
