What are condensation nuclei quizlet?
What are condensation nuclei quizlet?
Condensation nuclei are very small (about 0.2 – 10.0 microns) particles light enough to remain suspended in the air. Condensation nuclei are formed from a variety of sources including dust, pollen, smoke, salt from ocean spray and sulfates. . Hygroscopic nuclei are “water seeking” nuclei.
What is condensation nuclei?
condensation nucleus, tiny suspended particle, either solid or liquid, upon which water vapour condensation begins in the atmosphere. Nuclei that have diameters of several microns and are composed of a hygroscopic, or moisture-attracting, substance (e.g., sea salt) are called giant condensation nuclei.
What is the importance of condensation nuclei quizlet?
Cloud condensation nuclei promote condensation of water vapor at temperatures above and below the freezing point of water. CCN allow cloud droplets to grow and condense as condensation continues. Natural sources of CCN include ocean spray, volcanic eruptions, and forest fires.
Which of the following can act as a cloud condensation nuclei?
Examples of cloud condensation nuclei include sodium chloride (NaCl) and ammonium sulfate ([NH4]2 SO2), whereas the clay mineral kaolinite is an example of an ice nuclei. In addition, naturally occurring bacteria found in decayed leaf litter can serve as ice nuclei at temperatures of less than about…
How does condensation nuclei help clouds form quizlet?
Explain how condensation nuclei helps clouds form. These particles in the atmosphere provide objects around which water vapor can condense to form cloud droplets. (glomp) (platforms for which water particles to glommp onto. Low, dark, rain cloud.
What are hydrophobic nuclei?
Hydrophobic nuclei (1b) consist of particles such as oils and Teflon. These nuclei resist condensation even when the relative humidity is greater than 100 percent. These nuclei are hygroscopic (“water-attracting”) while others (oils, Teflon) are hydrophobic (“water-repelling”) (Figures 1a and 1b).
What is the meaning of nuclei in condensation nuclei?
: a small particle (as of dust) upon which water vapor condenses in the atmosphere.
What is hygroscopic condensation nuclei?
Hygroscopic nuclei are “water seeking” nuclei. Water vapor condenses on hygroscopic surfaces readily even when the relative humidity is considerably lower than 100 percent. Salt is an example of a hygroscopic particle. Hydrophobic nuclei are water repelling.
What is the importance of the condensation nuclei?
Condensation nuclei provide the non-gaseous surface necessary for water vapor to condense into cloud droplets. As droplets join together they grow larger and eventually fall as precipitation.
Why are condensation nuclei critical in the process of cloud formation quizlet?
16. Condensation nuclei act as surfaces upon which water vapor condenses. Saturated conditions are necessary for condensation and cloud formation. The cold glass cools the air in contact with it below the air’s dew point and water vapor condenses on the glass.
What serves as a condensation nuclei in the atmosphere?
Condensation nuclei are tiny atmospheric particles approximately 1/100th the size of a cloud droplet. They are formed by dust, soot, vehicle exhaust, wind storms, and numerous other activities that can stir up small materials into the atmosphere.
What role do condensation nuclei play in the formation of clouds quizlet?
Describe the process of cloud Formation. What role do cloud condensation nuclei play in the formation of clouds? -they are the base that lets water condense and form water droplets. Two ways that a parcel of air can reach saturation.
