Is a physical or chemical change a process?

Sublimation is a physical change.A substance can change from a solid to a gas without going through the liquid phase.This doesn't result in a chemical change.Dry ice has carbon dioxide in it.

Is it a physical or chemical property?Without changing the identity of the substance, physical properties are those that can be observed.The general properties of matter are examples of physical properties.Chemical properties such as Flammability are examples.

Is it possible to change a chemical property with heat?

A characteristic of matter that is not associated with a change in its chemical composition is called a physical property.Physical properties include density, color, hardness, melting and boiling points, and electrical conductivity.

There is a chemical change.The physical processes can interplay with the corrosive elements.When steel rusts oxidize, it expands and slowly separates from the underlying material, exposing more metal for rust.
