Sorting & Separation of Materials Quiz

Materials around us are made of different substances with varying properties. To use materials effectively, we often need to separate mixtures into their components. Separation techniques depend on the physical properties of the substances such as size, solubility, density, and magnetic properties. Common methods of separation include handpicking for large impurities, threshing for separating grains, winnowing for separating lighter particles, sieving for different-sized particles, sedimentation and decantation for insoluble solids in liquids, filtration for fine insoluble particles, evaporation for dissolved solids, and using magnets for magnetic materials. This Quiz on Sorting and Separation of Materials for Class 7th examines these practical techniques and their everyday applications. These methods are used in everyday life and industries. Learning about sorting and separation of materials helps students understand practical applications of physical properties and develop problem-solving skills. Answer these 10 multiple-choice questions to test your knowledge of separation techniques.
