It is a physical change, the chemical form remain unchanged.
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.
This is a chemical change because there is a molecular change in the composition. A physical change results when the size, shape, phase, texture etc. of a substance changes. Liquid water heated to water vapor is a physical change.
Yes. Any state changing is physical, unless it's a chrystal.
Crushing a lump of roll sulfur is a physical change, as the chemical composition of the sulfur remains the same. The process only alters the physical state of the sulfur without changing its chemical properties.
When sulfur combines with oxygen, it undergoes a chemical reaction to form sulfur dioxide. This is a chemical property of sulfur because it involves a change in the chemical composition of the substance.
physical changes~ cutting of paper, parked car, melting butter, flat basketball, and broken glass. chemical changes~burning gas, reacting iron with sulfur, vaporizing water.

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.
Yes. Any state changing is physical, unless it's a chrystal.
The melting point of sulfur at 112°C is a physical property. This property describes how the substance changes from a solid to a liquid state under specific conditions, without any change in its chemical composition.
Sulfur is a chemical element, not a property. Its chemical symbol is S and it is typically found in its solid form. It exhibits various chemical properties and can form different compounds with other elements.
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)
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.
It is a chemical property of sulfur because it involves a reaction with another substance to form a new compound. Chemical properties describe how a substance can undergo chemical changes to form new substances.
