A short note on Artificial rain<br> (100-150 words)
Wewaii [24]
It’s a practice of artificially inducing or increasing precipitation through clouds by adding external agents.

The foreign particles which are drenched over these clouds can be Dry Ice(solid carbon dioxide), Silver Iodide, Salt powder etc. This process is known as Cloud Seeding. This stimulation is done by aeroplanes or rockets. And then finally "rain on".

Agitation : The first stage includes the use of chemicals to stimulate the air mass upwind of target area to rise and form clouds. These chemicals absorbs the water vapour and helps in the process of condensation. Chemicals like - Calcium Oxide, compound of Urea and Ammonium Nitrate or Chloride Calcium Carbonate.

Building Up Stage : In the second stage the mass of the cloud is build up by urea, dry ice, kitchen salt etc to increase the density of the clouds.

Seeding : In the final stage of persuing the artificial rain, super cool chemicals (dry ice or iodide) are bombarded with the presurized canister onto the base of the clouds to build the beads of water and make them fall as rain.

yarga [219]

Answer:

The answer to your question is: V2 = 1.94 l

Explanation:

Data

V1 = 2.42 l

T1 = 25°C

P1 = 1 atm

V2 = ?

T2 = 25 -11 = 14°C

P2 = 1(0.7) = 0.7 atm

Formula

P1V1/T1 = P2V2/T2

Clear V2 from the equation

V2 = P1V1T2/ P2T1

V2 = (1)((2.42)(14) / (0.7)(25)

V2 = 33.88 / 17.5

V2 = 1.94 l
