Witryna12 sie 2016 · Melting is endothermic. 2. condensing - Condensing is the opposite of vaporization. Where does condensing occur? On the outside of your cold drink! Why? Because the molecules of water vapor touching the cold glass will lose their heat, slow down, and become liquid droplets. Therefore, condensation is exothermic, because …

Whether a process can occur spontaneously depends not only on the enthalpy change but also on the entropy change (∆S) and absolute temperature T. If a process is a spontaneous process at a certain temperature, the products have a lower Gibbs free energy G = H – TS than the reactants (an exergonic process), even if the enthalpy of the products is higher. Thus, an endothermic process usually requires a favorable entropy increase (∆S > 0) in the system that overcomes the …
