Chemical reaction
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.
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.
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).
it would be physical change because physical change is when the substance stays the same
it would be physical change because physical change is when the substance stays the same
If form changes but identity doesn't change then it is a physical change.
it would be physical change because physical change is when the substance stays the same
The "blank form" could be "state".
Reactivity is a chemical property, not a physical change. It refers to the ability of a substance to undergo a chemical reaction with another substance. Physical changes involve alterations in the form or state of a substance without changing its chemical composition.
Changes of the matter that do not change the composition of the substance.
Physical changes are changes affecting the form of a chemical substance, but not its chemical composition.
