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)
The dissolution of sulfur in carbon disulfide is a physical change because no new substances are formed. The sulfur particles are still sulfur particles, they are just dispersed within the carbon disulfide, similar to dissolving sugar in water.
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.
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.
The bright yellow color of sulfur is a physical property, as it is a characteristic that can be observed without changing the chemical composition of the substance.
No, using oxygen to separate molten copper sulfide into copper and sulfur dioxide is a chemical change because new substances with different chemical properties are formed. This process involves a chemical reaction where the copper sulfide is broken down into copper and sulfur dioxide molecules.
When heating sulfur, a chemical reaction occurs. Sulfur undergoes a phase change from solid to liquid to gas as it is heated, but this is still considered a chemical change because the molecular structure of the sulfur is altered in the process.
Simply heating (warming) sulfur could be a physical change if nothing happens to the sulfur other than it just getting warmer, and when you remove the heat, it stays as the original sulfur. However, more likely than not, heating sulfur will cause a CHEMICAL change where the sulfur combusts and turns into sulfur dioxide (SO2).
It is not a chemical change, unless you heat it sufficiently to make it catch fire.
Burning of sulfur (or anything else) is a chemical change, not a physical change.
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.
It is a chemical change, an oxidation reaction.
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.
if you mean epsom salts (magnesium sulfate) then heating it will result in a decomposition reaction, where magnesium oxide (s) and sulfur trioxide (g) is formed. The decomposition reaction is therefore a chemical change.
It is not a chemical change, unless you heat it sufficiently to make it catch fire.
heating of sulfur in presence of oxygen (or air) is a chemical change.

No, this is a chemical change.
