When adding or taking away energy, in this case heat, the molecules begin to either speed up or slow down, by doing this it changes its states. So when it gets hot the water molecules begin moving so fast the it changes into gas and evaporates, for ice the molecules contract and don't move much its more of a vibrating movement.
Thyxotrophy is the process of changing tissue from a less pliable to a more pliable state. This concept can also be described as tissue mobilization or tissue manipulation.
It may change its measurable properties but a simple state change is brought on by an increase or decrease the energy content of the material and does not alter the material from one material to another.
I think it can be classified as either a Chemical Reaction. Or an Endothermic reaction. I may not be understanding the correct queston though.
Examples:- the state of matter- the chemical composition- the chemical properties- the physical properties
Evaporation is changing of liquid state into gaseous state. Sublimation is changing of solid state into gaseous state.
If it is melting, boiling, condensing, subliming, or depositing, then it is changing state.
Motion

changes from one state to another without a change in chemical composition
When a substance changes from one state of matter to another it is called changing its state. Temperature changes are usually the main cause of this change.
When a substance changes from one state of matter to another it is called changing its state. Temperature changes are usually the main cause of this change.
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).
The word you are looking for is "transition." It refers to the process of changing from one state, form, or condition to another.
the action of changing or the state of being changed into another form: the transmutation of the political economy of the postwar years was complete. • Physics the changing of one element into another by radioactive decay, nuclear bombardment, or similar processes. • Biology, chiefly historical the conversion or transformation of one species into another. • the supposed alchemical process of changing base metals into gold.
Ice melting, water boiling and cutting paper. It usually has to do with changing the shape or state of the matter.
