Evaporation and condensation are thermodynamic eventsthat occur under the influence of temperature and pressure variables. Gases tend to condense at high pressure and low temperature. However, evaporation can occur at any temperature. This suggests that the temperature variable is more effective in condensation. For a system in equilibrium, the chemical potentials of the liquid and gas phases are equal to each other. The chemical potential, which encompasses the change in entropy of the particles and the effect caused by the change in enthalpy separately, corresponds to the molar Gibbs energy for a pure substance. In this context, the spontaneity of evaporation and condensation must be directly related to entropy change and temperature in order to fully conceptualize them. The aim of this study is to compare the spontaneities of evaporation and condensation at atmospheric pressure, considering the temperature and entropy change of the environment, and also to correct common misconceptions about these two processes.
