Match the following: Property Example Breaks easily ( brittle) Metal pan Bends readily Rubber band Can be stretched easily Cotton wool Gets compressed easily Mud pot Gets heated readily Plastic wire

Mud pot breaks easily ( brittle). Mud pot mainly made up with clay Mud pot mainly made up of clay and they have a great affinity for water. Plastic wire bends readily, flexible nature Rubber band can be stretched easily but regains the shape once the pressure is released. Cotton wool gets compressed easily because intermolecular space is very high. Metal pan gets heated readily because metals are good conductors of heat. Property Example Breaks easily ( brittle) Mud pot Bends readily Plastic wire Can be stretched easily Rubber band Gets compressed easily Cotton wool Gets heated readily Metal pan

Match the following: A B C (i) Separation of visible undesirable components water mixed with chalk powder Magnetic Separation (ii) Separation of heavier and lighter components sand and water Decantation (iii) Separation of insoluble impurities iron impurities Filtration (iv) Separation of magnetic component from non- magnetic components. rice and stone Hand-picking (v) Separation of solids from liquids husk and paddy Winnowing

(i) Hand-picking is used to separate undesirable components like rice and stone. Since there is a difference in size, we can easily hand pick undesirable stones from the mixture. (ii) Winnowing is used to separate heavier and lighter components like husk and paddy. Since is lighter in weight, it is easily blown away by the wind . (iii) Filtration is used to separate insoluble impurities like chalkpowder and water. As chalkpowder is insoluble in water and can be easily filtered out. (iv) Magnetic Separation is used to separate magnetic component from non- magnetic components. Since iron is magnetic in nature it can be easily separated out from a mixture. (v) Decantation is used to separate solids from liquids like sand and water. It means carefully pouring out of impurities.
