Is Vaporization Endothermic Or Exothermic - BRAINGITH

WitrynaIf a reaction is endothermic, the heat of the reaction is positive. If the reactants go from gaseous to liquid state, the entropy decreases (is negative). When the enthalpy is positive and the entropy is negative, the equation must always give a positive solution. Can entropy be positive? A positive (+) entropy change means an increase in disorder Witryna10 kwi 2024 · The vaporization of water is an endothermic process represented by Equation 1: vaporization_of_water.png My take on this well-known determination produces a value for the ΔH vap of water at 100°C to within a few percent of the accepted value. pinpoint portal
