Estimate the thermal conductivity of benzene at 30^{\circ} C.
Estimate the thermal conductivity of benzene at 30^{\circ} C.
Molecular mass = 78
\text { Specific heat capacity }=1.75 kJ / kg ^{\circ} C
k=3.56 \times 10^{-5} \times 1.75\left(\frac{875^{4}}{78}\right)^{1 / 3}=\underline{\underline{0.12} W / m ^{\circ} C } (8.12)
Experimental value, 0.16 W / m ^{\circ} C
