Evidence from the paper
His data on bulk modulus as a function of temperature can be fitted by the equation: K_T = 264.4 x 10^4 - 0.026 T (15). Additionally, he determined the temperature dependence of K'0 as K'_T = K'_300 + 1.4 x 10^-4 (T - 300) (16)

note
Printed value 264.4 x 10^4 GPa appears to be a typographic error; likely 264.4 GPa. Value copied verbatim.
