1.	Describe the process of separation of mixture of iron fillings, camphor and sand.
Answer» Solution :Separation of the components of a mixture of iron fillings, sand and camphor Procedure : The mixture of iron filling, sand and camphor spread evenly in basin. A STRONG bar magnet is brought close to the mixture repeatedly. The iron fillings attracted by the magnet. The iron fillings cling to the magnet can be shaved off from the surface with help of piece of cardboard. The remaining constituents are COVERED with a INVERTED funnel whose outside surface is wrapped with moist filter paper and the open end of the steam of the funnel is plugged with a piece of paper of cotton to stop the PASSAGE of any vapours formed. Then the mixture is GENTLY heated. Camphor undergoes sublimation and get deposited on the cooler inside wall of the funnel and later on it is scrapped off. Sand is left behind in the basin. Thus all the constituents of the given mixture are scparated by magnetic separation followed by sublimation
