  2. Condensation - Wikipedia

    en.wikipedia.org/wiki/Condensation

    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 ...

  3. Systems-oriented design - Wikipedia

    en.wikipedia.org/wiki/Systems-oriented_design

    SOD is an approach that addresses the challenges the designer faces when working with complex systems and wicked problems, providing tools and techniques which make it easier for the designer to grasp the complexity of the problem at hand. With a systems-oriented approach towards design, the designer acknowledges that the starting point for the ...

  4. Lifting condensation level - Wikipedia

    en.wikipedia.org/wiki/Lifting_condensation_level

    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 ...

  5. Humidity - Wikipedia

    en.wikipedia.org/wiki/Humidity

    Condensation can pose a safety risk as it can promote the growth of mold and wood rot as well as possibly freezing emergency exits shut. Certain production and technical processes and treatments in factories, laboratories, hospitals, and other facilities require specific relative humidity levels to be maintained using humidifiers, dehumidifiers ...

  6. Ice lens - Wikipedia

    en.wikipedia.org/wiki/Ice_lens

    This brief moment of exposure causes a thin layer of ice to form. When that formation is suspended in the air by dead vegetation or erect objects, the ice will begin to form a sphere or teardrop-like shape. Similar to how a condensation nucleus forms, the sphere needs a base that is not water. Most commonly on vegetation, the sphere starts as a ...

  7. Damp (structural) - Wikipedia

    en.wikipedia.org/wiki/Damp_(structural)

    Detail showing some of the causes of damp penetration. Structural dampness is the presence of unwanted moisture in the structure of a building, either the result of intrusion from outside or condensation from within the structure.

  8. Sol–gel process - Wikipedia

    en.wikipedia.org/wiki/Sol–gel_process

    By definition, condensation liberates a small molecule, such as water or alcohol. This type of reaction can continue to build larger and larger silicon-containing molecules by the process of polymerization. Thus, a polymer is a huge molecule (or macromolecule) formed from hundreds or thousands of units called monomers. The number of bonds that ...

  9. Vapour-pressure deficit - Wikipedia

    en.wikipedia.org/wiki/Vapour-pressure_deficit

    If a film of water forms on a plant leaf, it becomes far more susceptible to rot. On the other hand, as the VPD increases, the plant needs to draw more water from its roots. In the case of cuttings, the plant may dry out and die. For this reason the ideal range for VPD in a greenhouse is from 0.45 kPa to 1.25 kPa, ideally sitting at around 0.85 ...
