A sample of liquid benzene at 80°C and a sample of gaseous benzene at 80°C will have the same average kinetic energy of benzene molecules.

Let us recall that the average kinetic energy of molecules depends on the molar mass of the substance as well as the temperature of the substance. We have that;

average kinetic energy= [tex]\frac{3RT}{2NA}[/tex]

R = gas constant

NA =Number of molecules

M = Temperature in Kelvin

We can see that the average kinetic energy depends on temperature therefore, a sample of liquid benzene at 80°C and a sample of gaseous benzene at 80°C will have the same average kinetic energy of benzene molecules.
