What material is usually used to provide condensation nuclei in artificial rainmaking?
The resulting water vapour deposits into ice crystals, which build quickly as water droplets attach themselves. In clouds at temperatures above freezing, calcium chloride particles provide the condensation nucleii around which raindrops form.
What can be used as condensation nuclei?
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.
Which types of condensation nuclei are especially good for condensation to form?
Dust is needed for condensation nuclei, sites on which water vapor may condense or deposit as a liquid or solid. Certain types and shapes of dust and salt particles, such as sea salts and clay, make the best condensation nuclei.
What is the term for when condensation begins?
The temperature at which condensation begins is called the. dew point.
What does silver iodide do?
Silver iodide or dry ice (solid carbon dioxide) is used to supply naturally deficient clouds with the proper concentration of ice crystals to increase rainfall through the ‘cold rain’ process.
How do you make artificial clouds?
Make a Cloud in a Bottle
- Materials. Transparent glass jar.
- Form the water vapor. Fill a jar with 2 inches (5 cm) of warm water and stir.
- Form smoke particles. Ask an adult to light a match, blow it out and quickly drop it into the jar.
- Cool it.
- Watch the cloud appear.
- Make it disappear.
- The real deal.
Which is the 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 cloud condensation nuclei made of?
The particles may be composed of dust or clay, soot or black carbon from grassland or forest fires, sea salt from ocean wave spray, soot from factory smokestacks or internal combustion engines, sulfate from volcanic activity, phytoplankton or the oxidation of sulfur dioxide and secondary organic matter formed by the …
Which type of condensation nuclei are most likely to cause clouds to form?
These salt particles are the type of condensation nuclei that are most likely to cause clouds to form. Salt particles in the atmosphere provide a good non-gaseous surface where water vapor can transition into liquid.
How is condensation made?
Condensation happens one of two ways: Either the air is cooled to its dew point or it becomes so saturated with water vapor that it cannot hold any more water. Dew point is the temperature at which condensation happens. When warm air hits the cold surface, it reaches its dew point and condenses.
