✦ Synopsis

Measurements of the velocity of sound in saturated and compressed fluid methane are reported. Measurements were made on the saturated liquid from 91K to 186 K and on the compressed fluid along selected isotherms from 100 K to 300 K at pressures to about 35 MN m "2. Data were combined with newly available PpT data to obtain the isentropic compressibility and the ratio of the specific heats. Measurements along the higher temperature isotherm were limited to densities greater than about 10 mole I "1 at 300 K increasing to about 14 mole I "1 at 210 K due to the large low pressure sound attenuation in methane.
