If form changes but identity doesn't change then it is a physical change.
The "blank form" could be "state".

A physical state refers to the form in which matter exists, such as solid, liquid, or gas. This classification is based on the arrangement and movement of particles within a substance.
In chemistry, the term "state" refers to the physical form in which a substance exists, such as solid, liquid, or gas.
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.
Photon matter is a form of energy, not a physical substance.
State
The gaseous form of a substance that exists as a liquid at room temperature is known as vapor.
it would be physical change because physical change is when the substance stays the same
