摘要：

The speeds of sound in gaseous 2-methylpropane have been obtained at temperatures between 251 K and 320 K from measurements of the frequencies of the radial acoustic modes of a spherical cavity. Perfect-gas heat capacities and second and third acoustic virial coefficients have been determined from the results. Second and third coefficients of the virial equation of state have been calculated from the acoustic virial coefficients. We also report vibrational relaxation times for 2-methylpropane. © 1991 Academic Press Limited All rights reserved.
