Question

water vapor is a polar gas whose diellectric constant exhibits an appreciable temperature dependence .The following table gives experimental data on this effect .Assuming that water vapor obeys the ideal gas law,calculate the molecular polarizability as a function of inverse temperture and plot it .from the slope of the curve ,deduce a value for the peranent dipole moment of theH2O molecule(express the dipole moment in coulomb-meters).

T(k)=393; 423; 453; 483;............;Preessure(cm Hg)=56.49; 60.93; 65.34; 69.75;..........;((epslon/epslon not)-1)*10^5=400.2; 371.7; 348.8; 328.7;...........;

Explanation / Answer

please post the table.........it would be helpful to solve the question
