Heating a mixture of iron and sulfur results in a chemical change. When heated, the iron and sulfur react to form iron sulfide, a new compound with different properties than the individual elements. This transformation involves the breaking and forming of chemical bonds, indicating that a chemical reaction has occurred. Thus, the process is not merely a physical change but a chemical one.
Heating is a physical process.
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.
This is a chemical reaction; oxygen is released.
physical change
No, it is a chemical change. The metal oxide formed is a new substance.
Heating is a physical change.
Heating is a physical process.
Heating a frying pan is a physical change. A chemical change is when you change the chemical properties. Heating the pan is only changing the temperature of the pan not the chemical make up.

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.
It is a physical change (sublimation).
Heating is a physical process but during heating some chemical reactions are possible.
This is a chemical reaction; oxygen is released.
yes it is a physical change. there is no chemical change
when you separate a substance from a mixture, it's a physical change... Technically, you can get it back in the mixture.
