Condensation is the change of the state of matter from the gas phase into the liquid phase, and is the reverse of vaporization. The word most often refers to the water cycle . [ 1 ] It can also be defined as the change in the state of water vapor to liquid water when in contact with a liquid or solid surface or cloud condensation nuclei within ...
A similar phenomenon occurs on a global scale for certain chemicals. When these chemicals are released into the environment, some evaporate when ambient temperatures are warm and blow around on winds until temperatures are cooler, when condensation occurs. Drops in temperature large enough to result in deposition can occur when chemicals are ...
This is a consequence of the fact that particle surfaces are not smooth on the molecular scale, therefore condensation only occurs about the scattered points of actual contacts between the two spheres. [2] Experimentally, however it is seen that capillary condensation plays a large role in bridging or adhering multiple surfaces or particles ...
The cloud point is analogous to the 'dew point' at which a gas-liquid phase transition called condensation occurs in water vapour (humid air) to form liquid water (dew or clouds). When the temperature is below 0 °C, the dew point is called the frost point, as water vapour undergoes gas-solid phase transition called deposition , solidification ...
The microscopic process of evaporation and condensation at the liquid surface. If vapor pressure exceeds the thermodynamic equilibrium value, condensation occurs in presence of nucleation sites. This principle is indigenous in cloud chambers, where ionized particles form condensation tracks when passing through. The pistol test tube experiment.

The convective condensation level (CCL) results when strong surface heating causes buoyant lifting of surface air and subsequent mixing of the planetary boundary layer, so that the layer near the surface ends up with a dry adiabatic lapse rate. As the mixing becomes deeper, it will get to the point where the LCL of an air parcel starting at the ...
The Santa Ana winds, which occur most often in the fall and winter, push dry air from over the inland deserts of California and the Southwest toward the coast, the National Weather Service said ...
