Abstract
The velocity of sound and the relative volume of N2 were measured simultaneously in a piston–cylinder apparatus along five isotherms from 247 to 321 K at pressures up to 22 kbar. The data were combined to yield a consistent equation of state from which accurate thermodynamic variables can be derived.Keywords
