[amp_mcq option1=”Silver Bromide” option2=”Ammonium Nitrate” option3=”Silver Iodide” option4=”All these above-” correct=”option4″]<\/p>\n

The correct answer is (d). All of these substances can be used for artificial rain.<\/p>\n

Silver bromide, ammonium nitrate, and silver iodide are all hygroscopic salts, meaning that they attract water molecules from the air. When these salts are dispersed into the air, they can form clouds and cause rain.<\/p>\n

Silver bromide is the most common substance used for artificial rain. It is a white, crystalline powder that is soluble in water. Silver bromide is also used in photography and as a component of some explosives.<\/p>\n

Ammonium nitrate is a white, crystalline solid that is soluble in water. It is used as a fertilizer, a component of explosives, and a propellant in rocketry.<\/p>\n

Silver iodide is a white, crystalline solid that is soluble in water. It is used as a photographic developer, a component of some explosives, and a cloud seeding agent.<\/p>\n

Cloud seeding is the process of dispersing silver iodide or other hygroscopic salts into the air to induce precipitation. Cloud seeding is often used to increase rainfall in areas that are experiencing drought.<\/p>\n","protected":false},"excerpt":{"rendered":"
