A setniempirical expression about isothermal bulk modulus, B_γ, for n-nonane is obtained on the supposition that a cluster made of liquid molecules vibrates like a hard sphere in the free surrounds it and the effect of pressure on the occupied volume of n-nonane is space which negligible.
The isothermal equation of state, B_γ=B_0[1+B(T)Pⁿ] is integrated to given an equation of state,
<원문참조>
where B_0 is bulk modulus, P = 0, B(T) + <원문참조>, B(T, P)=[B_γ/B_0]<원문참조>, K_θ=A'a_(a_0)^⅓ and K₁=A_(s₂)/3.
The parameters of the equation of state are determined by fitting this equation to the reported data about specific volume of n-nonane. The isothermal bulk moduli, calculated from above equation and parameters, are compared with reported ones.
