ORS is used to treat dehydration by keeping your body hydrated. You have learnt to prepare ORS at home in Curiosity, Grade 6. You may have wondered why every sip of your homemade ORS tastes the same, no matter how much …

Did you know?

• 💡 Water is called the "universal solvent" because it dissolves more substances than any other liquid on Earth.
• 💡 Hot water dissolves sugar faster than cold water because its molecules move with more energy.
• 💡 Oil and water separate because water molecules are strongly attracted to each other, repelling oil.
• 💡 Ocean water is a giant solution containing many salts, gases, and minerals dissolved in it.
• 💡 Crystal caves form when mineral-rich water solutions become saturated and slowly deposit amazing crystals.
