Yes, anything that changes what it looks like is a physical change, and anything that changes it chemically like burning is chemical.

Like many other materials, rubies can be melted (extremely high temperatures) molded into other Jewelry objects, and other things. These are all changes to it's physical form, I'm not sure about chemical changes though, except that getting rid of some of it's components (like aluminum), or adding new ones (such as iron) will change the composition into another substance. (Object Transmutation. Yes it is possible to change lead into gold. This is not a 'legend')
(to first contributor: melting is still a physical change, it only changes the form and the state it is in, it is not a chemical change, which changes the substance completely)

Is frying a chicken physical or chemical change?
Physical changes can be undone. It is not possible to unfry a chicken. The heat casues chemical changes in the meat and in any coating.
Is magnesium physical change or chemical change?

What are the two classifications for the changes that matter undergoes?
Physical changeschemical changesYou must understand that matter can be in any one of three PHYSICAL states, liquid, solid or vapor ( a gas ).Changing physical states is not a chemical change, but a direct result of heat or cold application.
What are physical changes in biology?
The physical changes do not belong to chemistry but there are two types of changes. The chemical changes and the physical changes. A chemical change it's to mix to liquids that will form a new product. Physical change is the change that changed somethings shape but not consistency.
Is warming chocolate a physical change or chemical change?
Warming chocolate is a physical change because it changes the physical state of the chocolate from solid to liquid without forming any new substances.

Why cutting of tree branches is physical change?
Because any chemical changes occur.
Is baking soda reacting with vinegar producing a gas a physical or chemical change?
It is a chemical changes, as is any sort of reaction.
Is cooking any onion a chemical reaction or physical?
Cooking an onion involves both chemical and physical changes. The heat causes physical changes such as softening and browning of the onion as well as chemical changes such as the breakdown of complex molecules into simpler compounds, resulting in new flavors and aromas.
Is growing plants physical change?
no physical change is ptting ice cream and milk and mixing it for a milkshake or burning a piece of paper.
Zinc has a hardness on the Mohs scale of 2.5 and a density of 7.13 at 25 is it physical or chemical change?
The hardness and density of zinc are physical properties, as they do not involve any change in the chemical composition of the substance. Changes in physical properties can be observed without altering the chemical identity of the material.
