Can anyone explain cloud seeding (Artificial Rain) ? [Application of colloidal solution]
Answers
Answer:
Well,
Explanation:
Artificial rain: In clouds, water vapors are present in mixture with the dust particles. The water molecules present in cloud have electric charge on them and are of colloidal size. Clouds are also colloidal.
So, if the charged on the molecules is neutralized somehow, they will start raining. Sometimes it is done by spraying some electrolytes over the clouds and the rain resulted from this is called artificial rain.
[Application of colloidal solution]
Colloidal solutions, are nothing but a mixture in which the substances are regularly suspended. However, a colloidal solution usually refers to a liquid concoction.
Medicine, purification of water, formation of delta, cleansing action of a soap, sewage disposal, smoke precipitation are best process of best application example.
Other applications:
- Blood is a colloidal solution and the stoppage of bleeding on applying ferric chloride solution is due to coagulation of blood forming a clot.
- Blue color of the sky is due to the scattering of light by colloidal dust particles in air Tyndall effect.
- Similarly, sea water looks blue due to scattering of light by the colloidal impurities present in sea water.
- Tail of comets is seen as a Tyndall cone due to the scattering of light by the tiny solid particles left by the comet in its path.
Answer:
Clouds are the colloidal solution. ... In the artificial rain, the clouds are sprayed by oppositely charged colloidal dust or sand particles or precipitates of silver iodide. This spraying neutralizes the charge on cloud resulting in coagulation of the water droplets which come down in the form of rain.
