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).
Correct, any phase change is considered to be a physical change.
Heating is a physical process.
physical change
Heating a substance can result in either a physical change or a chemical change. A physical change does not alter the substance's composition, such as melting or boiling, while a chemical change leads to the formation of new substances with different properties, such as burning or baking.
1. Mixing iron and sulfur at room temperature is a physical procedure. 2. By heating a reaction occur and this is a chemical process.

Heating is a physical process but during heating some chemical reactions are possible.
It is a physical change (sublimation).
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.
Burning sulfur, or burning anything, is a chemical change.
