Chemical Changes result from the combining of two or more substances with a chemical reaction.
The end product can often be very different than the reagents.
For example, when Oxygen and Hydrogen are combined to form water, the product has a much higher freezing point or boiling point than the reagents, and has many other different properties.
Of course, with larger molecules, it is possible the product would resemble at least one of the reagents.

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 food a chemical change?
food is a chemical change if it is added with other components and turned into a form and if it is taken raw then it is not chemical change because no change is occuring
What is a change that alters the form or appearance of a substance but does not make it into other substance?
It is considered a physical change. A chemical change involves chemical reactions that change the substance into another substance. A physical change typically only modifies the form or phase.
Why is a state change not a chemical change?
You're only changing the form of the substance, not the chemical compounds in it.
