For 10 points, name this property referring to the changes in volume of a substance in response to changes in pressure.
One variable named for this property appears in the numerator of an integral added to the natural logarithm of pressure to yield the natural logarithm of fugacity, and an equation named for this property relates the two-body direct correlation function to temperature. Using Kay's rule, the computation of pressure times observed molar volume over the product of the gas constant and temperature yields this property's namesake factor, and at Mach numbers below 0.3, the effects named for this property are considered to be negligible. The coefficient of this property is equal to negative one over volume times the partial derivative of volume with respect to pressure.
