View SolutionMelting point,enthalpy of vaporisation and viscosity data of $H_2O$ and $D_2O$ is given below.
$Property$ $H_2O$ vs $D_2O$ $Melting$ $point/K$ $273.0$ vs $276.8$ $Enthalpy$ $of$ $vaporisation$ $at$ $(373 \ K) / kJ \ mol^{-1}$ $40.66$ vs $41.61$ $Viscosity/centipoise$ $0.8903$ vs $1.107$
On the basis of this data,explain in which of these liquids intermolecular forces are stronger?
