When iron and sulphur are heated at high temperature, a Chemical reaction takes place during the healing process. Sulphur (s) melts and reacts with iron (Fe) and undergoes an exothermic reaction to form iron or ferrous sulphide (FeS) which is black in color.
You get generally these option to choose from
(a) Black colored FeS is formed
(b) Mixture of iron and sulphur is obtained
(c) Yellow colored iron sulphide is formed
(d) They do not heat.
Answer (a) Black colored FeS is formed
Explaination:
When iron and sulphur powder are combined and heated, a chemical reaction takes place, Which results in forming of ferrous sulphide (FeS). It’s a totally separate chemical with qualities that are not common in Fe or S. This is because heating a powdered iron and sulphur combination results in a chemical change. Sulphur dioxide, an unpleasant, poisonous, and suffocating gas, may be produced by burning both solid and molten sulphur. It depicts the exothermic reaction of two elements, iron and sulphur, to produce iron sulphide as a compound.
When you heat iron and sulphur together, you get iron sulphide, which is a chemical.
Fe+S→FeSFe+S→FeS
Answer
Black colored Iron Sulphide (FeS ) is formed

What happens when iron is heated to a high temperature?
Iron glows in red color when it is heated to very high temperature. When iron is heated in air it reacts with oxygen to form the compound iron oxide. Iron is a solid and oxygen is a gas.
What happens if sulphur is heated?
Sulphur starts to melt at 115oC. At 200oC, It starts vaporizing before reaching the boiling point. When it is heated above 445oC, it will ignite. Also the color changes from yellow to red and starts to boil at 400oC.
