What is always a characteristic of a chemical change but not always a characteristic of a physical change?
When a chemical change takes place, the chemical structure of particles involved changes (i.e. one or more new substances are formed).
In a physical change, the physical state of the particles involved changes (e.g. a solid melts and becomes a liquid). The chemical structure of the particles does not change, and no new substance is formed.

Is the eye color physical or chemical change?
Eye color is a physical change, not a chemical change. Eye color is determined by the amount and distribution of melanin in the iris, which is a physical characteristic that can change over time but does not involve any chemical reactions.
Is pressure a physical change or chemical change?
A physical change. The chemical make up of the material is not changed. --------------------------------------------------------------------- Pressure is not a change, it is a characteristic. It is the ratio force/area.
Is freezing point physical property a physical change a chemical property or a chemical change?
The freezing point is a physical property because it describes a characteristic of a substance (temperature at which it freezes) without changing the chemical composition of the substance. When a substance freezes, it undergoes a physical change from a liquid to a solid, not a chemical change.
Which is a characteristic of chemical equilibrium but not physical equilibrium?
Reversibility of reactions is a characteristic of chemical equilibrium but not physical equilibrium. In chemical equilibrium, the forward and reverse reactions continue to occur, while in physical equilibrium, there is no net change in the physical state of a substance.
Is purple color a physical and chemical change?
No, the color purple is a physical property of an object that results from the absorption and reflection of certain wavelengths of light. It is not the result of a physical or chemical change, but rather the interaction of light with the object's molecules.
Is insoluble a chemical or physical characteristic?
Dissolution is physical change.
Is luster a physical or chemical change?
Luster is not a change, it is a characteristic.
Is melt lead chemical or physical change?
Physical. Melting is always a physical change.
Is the eye color physical or chemical change?
Eye color is a physical change, not a chemical change. Eye color is determined by the amount and distribution of melanin in the iris, which is a physical characteristic that can change over time but does not involve any chemical reactions.
How is a chemical and physical change similar?
they are both categorized under characteristic properties.
Is burning a diamond a physical change?
Burning is always a chemical change. Melting is a physical change.
Is burning gasoline a physical or chemical change?
Burnig things is always a chemical change.
Is rough texture physical or chemical property?
Coarseness is a characteristic, not a change.
Is pressure a physical change or chemical change?
A physical change. The chemical make up of the material is not changed. --------------------------------------------------------------------- Pressure is not a change, it is a characteristic. It is the ratio force/area.
Is burning wax a physical or chemical change?
Burning wax is a chemical change. If you are burning something, it will always be a chemical change.
Is freezing point physical property a physical change a chemical property or a chemical change?
The freezing point is a physical property because it describes a characteristic of a substance (temperature at which it freezes) without changing the chemical composition of the substance. When a substance freezes, it undergoes a physical change from a liquid to a solid, not a chemical change.
A characteristic of a substance that does not involve a chemical chance such as density color or hardness?
Physical Change
