It is a physical change, the chemical form remain unchanged.
Grinding sulfur is a physical change.
Physical change- it is still sulfur
Physical - because melting isn't a change in it's chemical structure, it has just changed its physical state of matter. Generally (but not always) physical changes are reversible (can be taken back) but chemical ones cannot be reversed easily.

physical changes~ cutting of paper, parked car, melting butter, flat basketball, and broken glass. chemical changes~burning gas, reacting iron with sulfur, vaporizing water.
Neither. Sulfur is an element by it self , that has its own physical and chemical properties.
Heating sulfur (yellow form, S8) gives initially a red liquid which solidifies as a rubbery mass. This is termed plasic sulfur. This slowly reverts back to the yellow form. These changes are considered to be physical changes although the molecular form changes (it is still sulfur) from S8 to a metastable polymeric plastic sulfur. There is often ignition of the sulfur - to form sulfur dioxide this is most definitely a chemical change.

Physical change- it is still sulfur
Cutting hair and shampooing hair are purely physical changes. However curling or straightening hair involve chemical changes too (i.e. sulfur crosslinks move). Dyeing hair is also chemical.

Heating sulfur is a physical change. You're not changing the chemical composition of the sulfur, just the temperature. Now if you heat it to its boiling point and and it changes to a vapor it's a chemical change because you've changed its state of matter.(Actually changing the state of matter of an object is still a physical change, as it does not change the chemical composition of the element)
Burning of sulfur (or anything else) is a chemical change, not a physical change.
It changes into a compound. You start with two elements and then when you heat them it changes to a compound. A compound is something that has new chemical and physical properties
