Temperature and Pressure Dependence of the Molecular Sound Velocity and Compressibility in Liquid Alkanes. II

抄録

The variations of the molecular sound velocity R and the molecular compressibility B have been examined in liquid alkanes in the temperature range −20 to 200°C and at pressures upto 1400 bars. At zero pressure they showed a decrease while at higher pressures an increase. A nonlinear increase with pressure is also noticed.
