Question

Artificial rain is made by spraying salt over cloud?

Answer 1

The process involved in artificial rain-making involves three easy-to-understand stages. The first stage is agitation. That is using chemicals to stimulate the air mass upwind of the target area to rise and form rain clouds.

The chemicals used during this stage are calcium chloride calcium carbide, calcium oxide, a compound of salt and urea, or a compound of urea and ammonium nitrate. These compounds are capable of absorbing water vapour from the air mass, thus stimulating the condensation process.

The second stage is called building-up stage. Here the cloud mass is built up using chemicals such as kitchen salt, the T.1 formula, urea, ammonium nitrate, dry ice, and occasionally also calcium chloride to increase nuclei which also increase the density of the clouds. In the third stage of bombardment chemicals such as super-cool agents: silver iodide and dry ice are used to reach the most unbalanced status which builds up large beads of water (Nuclei) and makes them fall down as raindrops.

Answer 2

Actually in creating artificial rain silver iodide is sprayed over the clouds by means of aeroplanes .The silver iodide creates a cooling effect on the clouds thus causing the water vapour in it  to condense and ...result=rain

Answer 3

Clouds are water dispersed in gas. Spray of salts causes their coagulation and thus water drops are formed which rains.
