Video answer for \Delta_{\text {vap }} \mathrm{H}^{\Theta} for water is +40.79 \mathrm{kJ} \mathrm{mol}^{ 1} at 1 bar and 100^{\circ} \mathrm{C}. Change in internal energy for this vapourisation under Calculation of Enthalpy of Vaporization at a Given Temperature Delta S` for vapouization of 900g water (in KJ K ) is `Delta H_(Vap)=40KJ(mol)^ 1 ` Plot the following data, and from the graph determine Delta Hvap for magnesium and lithium. In which metal is the bonding stronger?
