The mixture of sand and naphthalene can be separated by the method of sublimation.
The change of matter directly from the state of solid to gaseous or vice - versa is known as sublimation.
Naphthalene is a volatile substance that undergoes sublimation while the sand doesn't.
So, when the mixture of naphthalene and sand is heated over a flame, naphthalene undergoes sublimation and settles on the cooler portion of funnel kept inverted over the china dish.
The other substance left over in china dish is sand. Hence, the mixture of naphthalene and sand has been separated using the method of sublimation.
