Question

how can we separate a mixture of iodine and sand​

Answer:

Iodine is a solid that sublimes. If a mixture of iodine and sand is heated in a beaker, the iodine changes from solid to vapour directly. The vapour changes back to solid directly on a cold surface. The sand is not affected by the heat and remains in the beaker.
