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.
Example of physical change in an object?
A physical change is a change which affects only the physical properties of an object, not its chemical properties. Examples include breaking glass, smoothing a rock with a sander, and freezing water. As long as a new substance is not created in a process, the process is a physical change.
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.

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.
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.
