What occurs when water vapor condenses to liquid water?

When water vapor condenses to liquid water, the process involves a phase change where gas transforms into liquid. This transformation is accompanied by the release of energy in the form of heat. During condensation, water molecules lose kinetic energy as they transition from a gaseous state, where they are more energetic and spread apart, to a liquid state, where they are closer together and have less kinetic energy.

The release of heat into the environment occurs because the energy that was previously stored in the vapor as latent heat is expelled. This heat release can affect the surrounding environment, leading to temperature increases. This concept is fundamental in understanding processes such as cloud formation and the behavior of weather systems.

The other options focus on different energy dynamics that do not apply in this context. For instance, heat absorption does not occur; rather, energy is released during the process. A change in energy always accompanies phase transitions, so stating there is no change is inaccurate. Moreover, energy conversion to work does not take place in this specific phase change process, as the energy is mainly released into the environment rather than performing work.
