Salt is obtained by keeping seawater in shallow pits and exposing it to sunlight and air. The water evaporates, leaving behind a solid mixture, from which common salt is further purified. NCERT Science Textbook Curiosity Science Session 2024-2025.
A magnetic field is an invisible force field around a magnet where magnetic forces are exerted. It is represented by field lines that emerge from the north pole and enter the south pole of the magnet.
Magnets attract or repel each other based on their poles. Opposite poles (north and south) attract, while like poles (north-north or south-south) repel. This behavior is due to the interaction of their magnetic fields.
Magnets are classified into three main types: permanent magnets, temporary magnets, and electromagnets. Permanent magnets retain their magnetism, temporary magnets lose it quickly, and electromagnets are magnetic only when an electric current flows.
Common salt is obtained from seawater, which is a mixture of salts and other substances dissolved in water. Chapter 9 Methods of Separation in Everyday Life Class VI NCERT Book Curiosity Science
Sieving is used to separate components of a solid-solid mixture that have different sizes, allowing the smaller particles to pass through while retaining the larger ones. Class 6 Science NCERT Chapter 9 Chapter 9 Methods of Separation in Everyday Life
No, sieving will not work effectively if the holes of the sieve are larger than the substances being sieved, as both fine and larger particles could pass through. NCERT Book Curiosity Science Class 6 Session 2024-2025.
The bigger particles, such as bran and small stones, remain on the sieve, while the fine flour particles pass through the holes. Chapter 9 Methods of Separation in Everyday Life Class VI NCERT Book Curiosity Science
Mami uses a sieve to remove bran and other impurities like small stones from the flour, ensuring that only fine flour particles are used in the dish. NCERT Book Curiosity Science Class 6 Class 6 Science NCERT Chapter 9
