3 Ways to Calculate Vapor Pressure wikiHow Delta Vap H Latent Heat of Vaporization Delta Hvap of Water calculated by corresponding states correlation What is E when 2.0 mole of liquid water vaporises at 100C? The heat of vaporisation, H vap. of water at 100C is 40.66 kJmol^ 1. Sarthaks eConnect Largest Online Education Community Standard enthalpy of vapourisation `Delta_("vap")H^( )` for water at `100^@C` is `40.66 kJ mol^( 1)`. The internal energy of vapourisation of water at `100^@C` (in kJ `mol^( 1)`) is (Assume water vapour to behave like Delta Whip Grape Gas Live Rosin AIO 1000mg Catalyst 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
