Addition of carbon disulphide to a mixture containing iron fillings and sulphur powder, leads to formation of a clear yellow solution when sulphurpowder dissolves in carbon disulphide, on gentle shaking. ... When the solution is allowed to evaporate, powder of solid sulphur is obtained.
So its physical change because there is no change in sulphur just temperature applied.

It is chemical change.
there become vast diference in characteristics when sulphur changed to carbon sulphide.
Carbon disulfide is a colorless volatile liquidwith the formula CS2. The compound is used frequently as a building block in organic chemistry as well as an industrial and chemical non-polar solvent. It has an "ether-like" odor, but commercial samples are typically contaminated with foul-smelling impurities.
Sulfur is a soft, pale yellow, odorless, brittle solid. It is insoluble in water, but soluble in carbon disulfide. It burns with a blue flame, oxidizing to sulfur dioxide. Sulfur exists in several crystalline and amorphous allotropes.
Neutrons in most abundant isotope:
16
