Questions and Answers
When water vapor condenses, the surrounding air becomes:
When water vapor condenses, the surrounding air becomes:
- cooler due to the loss of kinetic energy in the vapor
- warmer due to the release of latent heat (correct)
- hotter, as the condensation process is endothermic
- unaffected, as the temperature remains constant during condensation
