1. The correct method for obtaining salt from seawater is (B) Evaporation. Seawater is collected in shallow evaporation ponds and left under the sun. As the water evaporates, salt crystals remain behind. This natural process is commonly used in salt production. For more visit here: https://www.tiwariacRead more

  3. The correct answer is (B) Sand and iron nails. Magnetic separation is used to separate magnetic materials, like iron nails, from non-magnetic substances, like sand. A magnet attracts the iron nails, leaving the sand behind. This method is commonly used in industries and recycling processes. For moreRead more
