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.

Is mixing iron and sulphur chemical or physical change?
A simple mixing is a physical process.
Is mixing iron and sulphur a chemical or physical change?

Is burning of sulphur physical change?
no. burning of anything is a chemical change
Is burning sulphur a chemical or a physical change?
Burning sulfur, or burning anything, is a chemical change.
Is Burning of sulphur a physical change or chemical change?
Burning sulfur, or burning anything, is a chemical change.
Is burning of sulphur with oxygen a physical or chemical change?
Burning sulfur, or burning anything, is a chemical change.
Why is heating of sulphur considered as a physical change?
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).
When iron filings and sulphur powder are mixed both retain their indiviual property this change is?
1. Mixing iron and sulfur at room temperature is a physical procedure. 2. By heating a reaction occur and this is a chemical process.
Is it chemical or physical of sulphur and oxygen forming sulphur dioxide?
The formation of sulfur dioxide from sulfur and oxygen is a chemical change because new substances with different chemical properties are produced. The reaction involves the rearrangement of atoms to form a new compound, rather than just a physical change in state or appearance.
Is a lump of roll sulphur being crushed a physical or chemical change?
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.
Is a tree growing a chemical or a physical change?
First of all lets understand Physical & Chemical Change. Physical change can be reversed and the chemical properties of the two states remain the same. Chemical change cannot be reversed and the chemical properties of the two state are entirely different. Now lets get back to the question. Is growing a tree a physical or a chemical change. The growing of a tree requires chemical changes, primarily the conversion of water and carbon dioxide into cellulose and oxygen. So the growth results primarily from chemical changes.
What is the chemical composition of sulphur?
Sulphur is a pure element.
