The "blank form" could be "state".
When a substance changes from one physical form to another, we say the substance has undergone a phase transition. This can occur through processes such as melting, freezing, evaporation, condensation, or sublimation. Each of these transitions involves changes in energy and molecular arrangement, but the chemical composition of the substance remains the same.
If form changes but identity doesn't change then it is a physical change.

When a substance changes from one physical form to another, it has undergone a phase change. This can include processes like melting, freezing, vaporization, condensation, and sublimation.
Substance changes to form a new substance through a chemical reaction. This involves the breaking and forming of chemical bonds between atoms, resulting in the creation of new molecules with different properties than the original substances.

When a substance changes from one physical form to another, you say the substance has had a phase change or undergone a phase transition.

When a substance changes from one physical form to another, it has undergone a phase change. This can include processes like melting, freezing, vaporization, condensation, and sublimation.
A change that alters the form of a substance without changing it into another substance is called a physical change. This type of change does not involve a change in the chemical composition of the substance, only its physical appearance. Examples include changes in state (solid to liquid) or changes in shape (cutting or crushing).
This is called synthesis, a combination chemical reaction that changes the chemical bonds in the substances.
It is a chemical property of sulfur because it involves a reaction with another substance to form a new compound. Chemical properties describe how a substance can undergo chemical changes to form new substances.
On the contrary, energy frequently changes from one form to another.
