Is oxidizing a physical or chemical change?
Oxidizing is a chemical change, as it involves a substance reacting with oxygen to form new compounds with different properties. In contrast, physical changes do not alter the chemical composition of a substance.

What is a change that alters the form or appearance of a substance but does not make it into other substance?

What is the definition chemical change?
Chemical ChangesAs opposed to a physical change, chemical changes are present when the substance undergoes a chemical reaction and produces a new substance. A chemical change is a chemical reaction that will always take place for there to be a chemical change. Signs that a reaction is taking place: Formation of gases (bubbles), Color change, production of heat or light, and the formation of a solid. a change in composition and characteristics of matter.new substance maybe formed.original substance and form may be lost.new color and shapeExamplesFermentationPhotosynthesisRusting nailSpoiling milkDigesting food
Why is a state change not a chemical change?
You're only changing the form of the substance, not the chemical compounds in it.
What kind of change form new substance?

Is it a chemical reaction when a substance changes its form?
The change of form in not a chemical process; it is only a physical change, the molecules remain unchanged.
Is oxidizing a physical or chemical change?
Oxidizing is a chemical change, as it involves a substance reacting with oxygen to form new compounds with different properties. In contrast, physical changes do not alter the chemical composition of a substance.
Is a change that produces a new substance is a chemical change?
False. This is a chemical change. A physical change is, for example, when Ice melts into water. It is the same element but it is in a different form. A chemical change is, for example, when two hydrogen atoms and an oxygen atom come together to form a water molecule, thereby producing a new substance.
