yes,sometimes both changes occur together. For example, when a person eats chocolate and then digests it a physical and a chemical change takes place. When the person chews the chocolate and breaks it into smaller pieces - it is a physical change. No new substances have been formed yet.Once acted upon by saliva and other digestive juices, the chocolate is broken down into other simpler substances, which can be absorbed by the blood. This is a chemical change.

Is length of an object a physical or chemical change?
The length of an object changing is a physical change, as it does not involve a change in the substance's chemical composition.
Is buoyancy a physical or chemical change?
Buoyancy is a physical change, not a chemical change. It results from the relationship between an object's density and the density of the fluid it is placed in, causing the object to either float or sink.
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.
What is one major difference in a physical change and a chemical change is?
Physical change, changes the appearance or the surface. Chemical change, changes the minerals inside the object. Physical deals with the appearance and the surface. Chemical changes the structure of the minerals inside the object.
Is flettening a chemical change?
No, flattening is a physical change, not a chemical change. A chemical change involves a change in the chemical composition of a substance, whereas flattening simply changes the shape or appearance of the object.
Is length of an object a physical or chemical change?
The length of an object changing is a physical change, as it does not involve a change in the substance's chemical composition.
Different between physical and chemical change?
In a physical change the object changes appearance but in a chemical change the object turns into something different with different properties.
When an object does not react with hydrogen is that a chemical change or physical change?
Easy, chemical change.
Is size of an object a physical property a physical change a chemical property or a chemical change?
i am pretty sure it is a physical property! :)
Is buoyancy a physical or chemical change?
Buoyancy is a physical change, not a chemical change. It results from the relationship between an object's density and the density of the fluid it is placed in, causing the object to either float or sink.
Is an orange a physical or chemical change?
An orange is a physical object and is not any kind of "change"!
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.
Why is change of color a physical change?
Because a physical change just alters the appearance of an object, where as a chemical change alters the texture or state of an object.
Would freezing an object be physical change or chemical change?
Physical changes and Chemical changes are both the same - this would be a reversible change.
Is a glass breaking a chemical change?
A chemical change is when the molecules of an object / solution are changed. A physical change is when the object / solution is altered without molecular change. Breaking glass is a physical change.
Is freeze drying physical change or chemical?
Answer: It is a chemical change, it changes the actual composition of the object by removing water.
What is one major difference in a physical change and a chemical change is?
Physical change, changes the appearance or the surface. Chemical change, changes the minerals inside the object. Physical deals with the appearance and the surface. Chemical changes the structure of the minerals inside the object.
